For the last 1-2 weeks, my ARC USB gets "stuck" when left unattended for more than a few minutes.

Whatever snapshot light was last on, stays on, and buttons and the encoder are no longer responding when pushed. If I unplug and re-plug the USB it starts working again normally.

Nothing has changed in my setup except for windows updates. The ARC is connected to the PC because I keep a USB key for recording in the UCX-II.

I've tried updating the TotalMixFX to latest version and the Fireface UCXII firmware and all, but no luck.

Based on the timeline, one of these updates on Windows 10 22H2 (19045.4651) might have caused it:

• KB5040427 - Cumulative Update for Windows 10 22H2

• KB5041019 - Cumulative Update for .NET Framework 3.5, 4.8 and 4.8.1 for Windows 10 Version 22H2
