You’ve mentioned in the thread you’ve on Debian 12 - have you installed mesa from backports?
The version of mesa on 12 is is 22.3.6 which is before the release of the 7900GRE and only very early RDNA3 support.
bookworm-backports has 25.0.7
If you read through https://backports.debian.org/Instructions/ you can enable the backports repo then just reinstall mesa (or dist-upgrade)
They zigged when we all zagged.
Decentralisation has always been the answer.
