An unexpected error occurred( file ", line, function ")
- 1 year ago
There has been serveral bug reports about this - the issue was introduced in the March 2025 update.
It has not been fixed yet, even in the May 2025 release.
The general recommendation is, if possible, downgrade to the Feb 2025 version.

Just upgraded to the December 2026 release version and encountered this issue. Obviously still not resolved.

I believe the issue is not on the MS side of the fence. This is a hardware requirement on the user side, so they are not going to do anything in the updated versions.
To my understanding, it's related to supporting the AVX feature by your server/local machine CPU:
