Description

I recently had to fully reset my win 11 box. After installing everything I noticed that files does not even start. I added .net sdk 8 and also 7, but I can't get it to start. In eventlog I do see:

Application: Files.exe
CoreCLR Version: 8.0.324.11423
.NET Version: 8.0.3
Description: The process was terminated due to an unhandled exception.

Thanks for the report, are you using an unofficial (like Atlas OS or ReviOS etc.) or a modified (like disabled Windows update system, removed the Microsoft store, used a debloat program/script etc.) version of Windows? If so Modified versions of Windows are not supported.

The issue was not with the machine nor the OS... I had issues with my router, which failed to resolve certain ips; Windows update was also affected; so I restored it from an known to work image... so all is good again. Closing this issue as no longer relevant. Thanks for taking the time to look at it!
