0fps on empty scene with a 2080Ti. What's the issue?

I updated TM to the 2025 preview but, since then, the program goes to 0fps even on startup and empty scene.
I re-installed the previous versions (that previously gave me no issues) and now those too are 0fps.
Went back to the 2023 community edition but the issue persist.

What do?

System is
Ryzen9 3950X - 32Gb Ram - 2080Ti (566.36 DCH drivers)- SSD has mode than 100Gb free space.

attached screenshots for each version

quick update:
by mere chance I found out that I still had left installed the version “2023 1.2 Education” which seems to work just fine at 150-180fps
I also tested a couple of games (Control and Death Stranding) and both work fine.

The plot thickens

Still no solution with the more recent versions but it doesn’t seem an hardware-related issue

Apparently there was some sort of conflict with the Oculus/Meta software.
the issue seems to disappear after disinstalling that.
