Excel 2021 not responding

Copper Contributor


I've installed Office 2021 professional plus x64 (a fresh install) in my machine with windows 11 pro but Excel is not responding and is freezing. I've tried everything from the support page but without success.

What else can I do?

If could help, these are my pc specs:

Processor AMD Ryzen 7 3800X 8-Core Processor 3.90 GHz
Installed RAM 32.0 GB

It's bit strange what only Excel is not responding but other apps (Word, etc.) work. In any way I'd do clean reinstall Repair an Office application - Microsoft Support . It's mainly above 365 but shall be applicable to 2021 since it uses C2R. 

@Sergei Baklan Thanks for your reply.

Yes, Excel is the only app that don't work properly. I had the same problem with Office 2019, this is why I bought Office 2021 :( 

Anyway, I tried the solution you linked but without any success.


Sorry, if clean re-install doesn't work I have no other ideas.
