DOpus 13.18 / Win 11 PRO unstabile system after start DOpus

Hello and good evening,

Opus 13.18.1 / I unfortunately can't afford to update to the latest version
Windows 11 / PRO / 25H2

For about two days now, I've been experiencing the following problem:

As soon as Opus Directory is launched for the first time after Windows has started, the system becomes unstable.

With Opus itself, I can no longer switch tabs; instead, a lock or green checkmark appears.
Selecting the second or third file doesn't work; it always selects everything from top to bottom.
Double-clicking, right-clicking, and left-clicking with the mouse button no longer work.

The Desktop app only opens the properties.
With Firefox, I can't close any tabs, and settings or plugins are no longer accessible.
Windows becomes unstable, and almost no programs can be used.

As long as Opus isn't running, everything works fine.

I hope someone here can help me.

Christian

Nothing Opus does should affect Firefox in that way, and if it has only started recently it must be caused by a change in (or installation of) something else, since Opus 12.18 hasn’t changed in a much longer time.

What other changes have been made to the machine around the time the problem started?

I don't think it's my fault.
I'm not sure after an update from windows himself possible.
I don't check first, and ff is stable also windows if not started Opus.
I work without Opus now 6 hours and no problem.
This Morning 6 times reboot. Yesterday I turned off after I was so frustrated.
Today I try to find out with choice this start and still work other start still work
3 times I try and always after started Opus.

But i think its something with Windows UpDate and Opus was not work and no other software or hardware.

It could be something which is loading itself into both programs and going wrong when both are runnjng at the same time. I don’t know what, though, and our code doesn’t do anything to Firefox.
