Many people are reporting it as I see. Is the PC language non-english?

Hello, I have same issue, and yes, windows set non-english UI language.

I tried to force US language, but without result. I guess right now I must revert to win 10, set lang to US, and only then update to win 11

Hello there,

You can launch your File Explorer and go to search and type 'Task Manager' and press enter. Then you might see an option of File explorer in the new window that pooped up. Select it and there click on the option restart at the right bottom of the the window. And your problem will be fixed. This has happened to me most of the times and I use this little trick to resolve it!

Thank you! I hope your problem might fix!

I found the solution. This particular issue caused by poorly installed cumulative updates. After Uninstalling issue was fixed. You should remove all updates from Microsoft Windows category besides "Servicing Stack 10.0.22.000.51" as shown on picture below

After that you need to change windows language to en-US, then download updates. If you have Win 10 Home SL (Single Language) you need download extra language pack thru DISM, and remove non English language from system
