It happens basically every time I upload certain workspaces to FME Server

Just checking, the versions of FME Desktop and Server are the same?

Yes, the versions are the same desktop/Server

Hi @jan. I'm sorry that you're experiencing this crash. Some additional questions to help assess the issue:

1. What operating system are you using?
2. Have you successfully published a workspace to FME Server in the past?
3. Are you experiencing the crash when uploading only particular workspaces and/or services, and have success with others?
4. At what stage of the publishing wizard are you experiencing the crash?
5. Is FME Workbench crashing and not just the publishing wizard? If you get an fme.exe error, can you send a screenshot of the error details? The "Fault module" might help us narrow down the issue.
6. Do you see any errors in the translation log, or in FME Server?

I had the same issue a while ago when I tried publishing an unsaved workspace.

Try saving the workspace before you publish to FME Server.
