SOLVED: Fusion 9 (non studio) unusable freezes all the time

Can't say why, freezes randomly, it looks like it started after installing recent version of Davinci Resolve Studio (dongle one)

Can't even start new project as interface is not responsive for a while (like one minute sometimes)

Anyone had this issue? Reinstalled Fusion, but I can't reinstall Davinci atm, I am using it in other projects.

There is one strange thing I've noticed
I have two fusion.exe tasks running in my task manager - even if davinci resolve is not running.

I think it's solved.

Looks like in my preferences I had one referencing to drive which doesn't exist any more.
So removing preferences (which did survive reinstall of fusion itself) helped.

Seems that duplicate Fusion.exe in task manager is normal thing
