I installed the last version (twrp-3.7.0_12-1-ginkgo.img) on my Redmi Note 8T and bluetooth doesn't work anymore. Trying to go back to twrp-3.6.2_9-0-ginkgo.img doesn't solve the problem

I had the same problem. I changed rom from the last arrow to the last lineage. With clean flash everything work after 2 day's i change twrp from 3.7.0_12-1 to 3.6.2_9-0 i lost the Bluetooth.
I did clean flash again with twrp 3.6.2_9-0 and now no problem.

Thanks for sharing you experience.
While doing clean flash did you erase also data partition or only system?
Because I have some cloned apps but TWRP isn't able to decrypt user 999 and I don't know how to backup that data.
I just tried doing only a clean flash of recovery (3.6.2_9-0) but bluetooth still doesn't work

P.S.
Also tried erasing system and flashing official ROM from fastboot

Hi i erase both. First system and then data. My phone was empty from app and data and i didn't need backup.
