Can confirm. You could also try using the official Microsoft PC Health Check app's troubleshooting details, as it sometimes flags specific settings like Secure Boot that need enabling.

Yeah, I had the same problem. I used subprocess.run to start 'snippingtool.exe' and it launched perfectly for me.

Another option is to check if TPM 2.0 is enabled in your BIOS, since that's a common blocker the Health Check doesn't always explain clearly. Let me know if that works.
