That's FP waiting for Windows. When it takes longer, it's usually a third-party plugin initializing.

I have some things to try to mitigate these issues, but unfortunately, this whole architecture is broken. MS should not have allowed extensions to take over.

Would you recommend any app to "troubleshoot" these delays? Maybe a tool that helps seeing which extensions take long to load?

ShellExView can be used to track down slow extensions (but it doesn't offer runtime performance numbers):
