MF Utility v2.90 quits on program start

Hi there,
MF Utlity v2.90 just quits when I start it. It briefly shows up for less than a second in the Taskmanagers Details tab. I have no idea what may have changed. I reinstalled v2.85, and that worked just fine, so I'm using that.

Restarts didn't help. Reinstallation of v2.90 didn't help. Is there some config file I could delete. Happy to try stuff.

We are working on 2.91 which aims to fix some issues on W10 and 11. One thing you can try in the meantime is setting the MFU to run in compatibility mode. While being a .1 update, that new one has a major framework upgrade that should make it more stable on newer OS

Tried most of the compatibility modes to no avail.

Hey, are you guys putting in a device selection dropdown menu of some sorts for 2.91 ? I wouldn't mind :) .

I also have the 2.9 version utility that won't open; has there been an update? Is there somewhere to download the previous 2.85 version?

Thanks

Update : fixed - but only by manualy deleting the old files and re-installing
