Describe the bug

CKAN.exe fails to start. Running CKAN.exe results in immediate CMD Prompt with error (See "CMD Error") and an Error! window (see "Error! Window") pasted below. Closing the command prompt or pressing dismiss on the error window results in a crash to desktop with "CKAN-CmdLine has stopped working". KSP runs without issue if I run KSP_x64.exe directly.

Error! Window:

Thanks for the report, this was fixed in #3733.

[Mitokandria]

Thanks. I forgot to check the "include closed" button when searching for bugs.

Well, you'd also have to search pull requests in addition to issues, since this was reported on Discord instead of GitHub. It's not super easy to find.
