Powershell Synchronizer fails when triggerd by RDM UI, works via powershell

RDM Version: 2026.1.15
Devolutions.Powershell Version: 2026.1.3
Datasource: SQLite

Issue:
Running the Powershell Synchronizer from RDM UI fails with:
Could not load type 'Devolutions.RemoteDesktopManager.Theme' from assembly 'RemoteDesktopManager.Core, Version=2026.1.15.0, Culture=neutral, PublicKeyToken=null'.

Running with Open-RDMSyncSession -ID <ENTRY_ID> works.

i attached an export of a testscript and a test credential which shows the issue nicely.
The file is a RDM Export inside of a zip, as rdm files are not allowed as uploads.
Just import into a clean RDM and run the synchronizer, this will generate a logfile in your temp (exact path is visible in the code)

This logfile has a bunch of extra data as i use it for my generell debugging, but one of the lines is the error from above.
