Thank you very much, I'll try this tonight and see if formatting internal storage in TWRP fixes the problem. That's something I didn't do the 1st time.
7 months later I finally got this installed tonight and is working beautifully. I know there's a Android 12 version of this Rom now but I'm perfectly happy and satisfied with this one.
It is certified fast, stable and force close free.
If for any reason I have any issues I'll transition to the new version of this one instead.
I was very close to going out and getting a new Pixel 5A and replacing my tiamen because I gave up hope on flashing any Rom at all after so many issues on my end last year.
The way I was able to get this installed was with the PE recovery and not TWRP. Following the install instructions on the PE website and that's it. Truly flawless.
Many thank you to any and all involved with the development. We all owe you big time.
