Custom ROM Installed, Custom Recovery Dies

This is my first thread, I apologize for any mistakes or core aspects left out.
Intro/Formatting Key​Before I start, I want to give a quick thanks to those contributing to these forums/threads, as it got me through my first custom ROM install ever! Knowing too much information is better than too little, and my want to not waste anyone's time, I'm going to share most of my experience installing the custom recovery and ROM. I will explain what I mean by custom recovery dying at The Dead Recovery. Italics will be used as commands entered in SDK tools. Bold will be used as outputs from cmd.
Phone Specs​Phone: Oneplus 7T HD1905 running Android 11 OOS
Custom Recovery: Chinese TWRP from this youtube video
Custom ROM: Derpfest R for hotdogb found here
My Install Process​Besides needing to turning off driver signature reinforcement, the bootloader unlock was a normal process. Issues started occurring when I wanted to flash the custom recovery. fastboot reboot fastboot would not give me any feedback on the cmd prompt as it would say <waiting for devices> even though my phone was in fastbootd mode. After reading another thread, I hail married the flash using fastboot flash recovery twrp_best.img. All was great! My phone booted into TWRP, wiped the old stuff, flashed Derpfest, and rebooted. Derpfest works pretty well! (a little buggy but what do you expect from a beta build?).
The Dead Recovery​I notice the safety net with this ROM was broken, so I wanted to install Magisk to fix that issue (I wanted to use Gpay). I download the apk, do my renames for .zip and unintall.zip, and attempt to boot to recovery, but I just get a black screen! Using PWR+VOLUP allows me to reboot into the ROM just fine at least, so I didn't brick my phone. From here, I don't know what I should do to mitigate this issue. Here are my main concerns/questions.
Questions/Concerns​1. Will flashing a new recovery allow me to still boot into my phone?
2. Should I use a different image?
3. Should I maybe use flashboot flash recovery_a twrp_best.img flashboot flash recovery_b twrp_best.img to flash the recovery?
Thank you in advance!​

Realme 6 Pro stuck on infinite bootloop at fastboot

I forgot to wipe data after flashing stock ROM(that proved to be a huge mistake). My bootloader is unlocked. I tried flashing stock ROM recovery and Orange fox recovery but it always bootloops to fastboot way sooner than I can finish all of my steps. Same case when I tried to erase boot it bootloops faster than the process to be finished.
Can anyone please suggest me any method to stop bootloops atleast in fastboot mode?
Use the volume+ and power button to turn the phone off and stop the bootloop.
Then ...
Use Realme Flash Tool v1.1.3 to re-flash the stock rom. Be patient and let it do its thing you will think it is not working or is stuck but just let it run to the end.

Question Soft Bricked (locked bootloader)

So, I tried to flash stock rom from project elixir, and I got soft bricked with the error of "The current image(boot/recovery) have been destroyed and can not boot. Please flash the correct image or contant custom service to fix it"
I can't enter the fastboot (I think?, idk i think i can't)
Anyone know how to solve that issue? Or only custom service?
Update: I get into fastboot for now and unlocked the bootloader, does anyone know is it any possible way to flash a custom rom or stock actually? (I can't boot into twrp and can't flash los recovery, after flashing los recovery when i get to reboot, I get fastboot bootloop)
Bro you should reach out the official realme service and flash stock rom it takes around 1 hour and 177 inr.
