[Bug] Crash after importing .ckan file, and on launch afterwards

[Osthekake]

Background

• Operating System: Windows 10
• CKAN Version: 1.27.0
• KSP Version: 1.8.1.2694

Have you made any manual changes to your GameData folder (i.e., not via CKAN)?
No

Problem

I get an error whenever I start ckan. This happens after I imported a .ckan on an install with no previous mods. The error further causes all my mods to be marked as "Remove" in the changelist. I can clear the changelist, but all the mods are added back whenever I select a mod for updating. This makes it impossible to update the mods in ckan, since it will always want to remove every mod.

Steps to reproduce

• Clean install. No mods.
• Import a .ckan list (Mine is provided)
• Error should appear now
• Close Ckan, open again.
• Error appears now as well.
• Every addon is in changelist to be removed

Expected behavior
No error message
All mods should not be added to be removed

Screenshots (if applicable)

CKAN error code (if applicable):
Pardon the Norwegian

I meant to, but I forgot. Updated issue now.
