Windows 11 may also have introduced an issue with Windows Smart App Control

How does Smart App Control work?
When you try to run an app on Windows, Smart App Control will check to see if our intelligent cloud-powered security service can make a confident prediction about its safety. If the service believes the app to be safe, Smart App Control will let it run. If the app is believed to be malicious or potentially unwanted, then Smart App Control will block it.
If the security service is unable to make a confident prediction about the app, then Smart App Control checks to see if the app has a valid signature. If the app has a valid signature, Smart App Control will let it run. If the app is unsigned, or the signature is invalid, Smart App Control will consider it untrusted and block it for your protection.

Icaps files are now signed which should resolve any Smart App delays but they may require updating from the internet.

You may prefer to disable the Smart App Control so that Win 11 doesn’t keep submitting files to MS for analysis.
