You seem to either have a broken rpkg file or a mod using an older version of rpkg.
Verify the game files using Epic games. If that does not help, test if removing other mods helps. If you tell me the name of the conflicting mod I might be able to fix this in future versions. As a workaround, a patch level above 100 might work if you patched your packagedefinition.txt.framework-original.
