I would recommend checking again the requirements from the KB:

https://gateway.sdl.com/apex/communityknowledge?articleName=000002069

and maybe run a Passolo repair from Control Panel.

Hi Adrian,

Thanks for the reply. We have already verified the requirements were installed. We have tried re-installing Passolo from scratch, and it didn't help anything. We haven't tried a Repair, but I wonder if that would be any better than reinstalling from scratch... We've heard that there might be compatibility issues with Passolo 2018, Windows 11, and .NET Framework 4.8.... have you heard anything about that?

I've tried to access the SDLXLIFF export settings on Windows 11 machine and I see no issues.

We had an issue in the past like:
Is Passolo 2018 compatible with Windows 11? It crashes creating and removing glossaries but the issue was different and caused by Visual C++ not being installed correctly.

Maybe this would also help here. 

If not, I would recommend logging a support case and adding the Event viewer logs there or even here.

This is the event viewer info we get from the Passolo crash:

I'm afraid I don't see anything that could cause the issue from the Event viewer.

have you tried to re-install the Visual C++ redistributable?

Other thing that could cause the issue might be the antivirus or maybe user permissions. Maybe you can try to run Passolo as Administrator.
