This looks like an assembly binding issue. Are you using modules like EXO?
Adam Driscoll

Yes, this is using the EXO module.
We have a fix for the EXO module coming in 5.5. There is an assembly conflict at the moment. This release is coming out next Tuesday.

I updated to 5.5 and now I get a new error.

What version of the EXO module are you using?
Adam Driscoll
PowerShell Expert and Developer at Devolutions
I am using version 3.7.2
Can you try a couple things?
- Upgrade to PSU 5.5.2 - We had more assembly binding fixes and added some logging
- Ensure that your app is running in PowerShell 7 or the Windows PowerShell 5.1 environment
- If it still fails, open the agent logs in %ProgramData%\PowerShellUniversal\Logs. They will contain assembly binding information.

The upgrade to PSU 5.5.2 resolved the issue for me. I appreciate your help.
