Fingerprint scanner won't open settings

So when I open the fingerprint scanner in the settings it asks to enter the pattern and when I do it it opens another window asking for the pattern and keeps doing that. And when I back out I have to keep backing out depending on how many times I enter my pattern. I've tried clearing settings data as well as the fingerprint scanner data to no avail. Any suggestions?
I am also having this issue.
Any solution ?

How can I completely disable the fingerprint sensor?

I don't really like all the hype about the fingerprint sensor, I'd rather like to have it killed down, so that it doesn't have any chance register any fingerprints.
On a desktop Linux I'd simply `modprobe -r` the relevant kernel module. Can I do something like that on Android? I don't want to simply disable it in the settings - then I have to trust the system that nothing really uses it.
im not sure if this can be done. try to find the fingerprint set up apk. I believe if you delete this apk it will FC every time you try to register a fingerprint. other wise set a pin and you wouldn't be able to register fingerprint without knowing your pin.

[Help] Fingerprint reader stops working for 5-10 seconds randomly

I'm running stock OOS 9.0.8, unrooted.
In the last couple OTA updates, I have noticed issues with the fingerprint reader. I have a few apps with security settings that allow for opening the app with a fingerprint, and throughout the day, I will have periods where the fingerprint reader doesn't register prints. The fix so far seems to be locking the screen and hitting the fingerprint reader on the phone over and over until it registers a print, at which point the app unlocks with fingerprint start working again too.
I haven't figured out what exactly causes this, because the reader still works entirely fine, it's just that it stops reading occasionally for 5-10 seconds until I re-open the phone from the lock screen.
Anyone have any info on this? Thanks in advance!

Bizarre BUG HELP: Suddenly Can't set number/ pattern lock without adding fingerprint

Hi there, Please help me with this weird bug in my MM3's lock function. I haven't read about it anywhere else and I did not update or tweak my rooted system in any way so I'm at a loss as to what caused this probleman d how to fix it.
I am no longer able to employ a simple numerical or pattern screen lock. I go to settings, choose and then confirm the number or pattern, and hit accept -- at which point it asks me for a fingerprint (which I do not want to add) and when I hit cancel, the phone remains unlocked. If I hit add a fingerprint and refuse to present my finger, the phone also remains unlocked. This is so freaking weird!
(MM3 rooted but on stock Android 9 PKQ1.181007.001 -- Miui Global 11.0.6 Stable)
Honestly, I wouldn't give a damn as I never use a screen lock except I am in fact forced to use it every few weeks or whenever I want to review my Brave browser passwords. It forces me to set a lock screen in order to see them. So if there's a workaround just to see passwords, that would do me fine.
Because the basic number and pattern locks aren't functioning properly, I wouldn't even consider adding a fingerprint (and in fact, I have never done so. I have a probably irrational distrust of fingerprint, voice and retina security ... plus I live alone so such measures aren't necessary)
Can anyone give me any clues as to what could be causing this and how to fix it or get around it? Or even if there is a way to see my Brave passwords without employing a lock?
Theoretically, I could try temporarily installing a fingerprint lock which I could then remove after reviewing my Brave passwords. But I have an irrational dislike of fingerprint, voice and retina locks and never use that stuff. Moreover, given the basic number and gesture locks aren't functioning properly, the last thing I want to do is try a fingerprint.

Question Fingerprint enrollment

Hello,
i am having very frustrating time trying to enroll a fingerprint on the phone. This is my first phone with in-screen fingerprint reader so i am not sure if this is the intented implementation. I want to enroll two fingerprints of the same finger (thumb) for better accuracy. Enrolling first fingerprint is no problem, but when i try to enroll the second one, halfway (sometimes sooner, sometimes later) trough the enrollment process i cant help but press with the part of the fingerprint which is already enrolled with fingerprint 1 and the enrollment progress is reset which means i have to start over. I also get the message that this fingerprint cannot be enrolled becauise it is already enrolled fith fingerprint 1. Of course, when i try to enroll once again, the exact same thing happens again and again to the point that is almost impossible to enroll two fingerprints of the same finger. So far I have been using xiaomi phones with physical fingerprint readers and enrolling two or more fingerprints of the same finger was no issue at all.
Can someone confirm whether this happens with in-screen fingerprint readers or is this an OP thing? Thanks.

you don't need to register your finger twice, once is enough
