Since upgrading to TB 91 (currently 91.2.0), it consistently takes 5+ minutes to start [Windows 10 Pro x64 v. 21H1], even in Safe Mode (all extensions disabled). I can see the Disk Active time pegged at 100% in the Task Manager during this time, but little to no CPU usage. I am using F-Secure Security Suite for AV (rebranded for Spectrum). Suggestions as to how to fix this?

I see I posted this in the wrong forum - is there an easy way to move?
