Windows 11 keeps rejecting Thunderbird

I run a dual boot system with Ubuntu on one side and Windows 11 on the other side. So far, I've had no problems with Thunderbird in Ubuntu. However, I am having nothing but problems in Windows 11. I have downloaded and installed Thunderbird numerous times in Windows. On the day that I install the software, the program runs properly. However, every time I shut down and restart the system the following day I receive this message: "This app can't run on your PC." I have tried installing the program specifically as an administrator and it has made no difference. All of the program data, including my email accounts, are still there if I reinstall the software. I have also have this problem with Revo Uninstaller and Avira anti-virus software. This has been on-going for the last month or so. Does anyone have any ideas about what could be causing this or how to fix it???

Strictly speaking, sharing a profile across OS is not supported.

Please post a screen shot of the error, or provide the exact wording.

The only thing that is shared is the IMAP email accounts. I have done this for a long time without problem. As I stated in my first post, I'm receiving this error (exact wording): "This app can't run on your PC." It has done this for Thunderbird and other programs randomly. I just can't seem to figure out why.
