Not sure if it's important, but the reported windows version is incorrect. I am on Windows 11, version 22H2

The error also seems to affect the character editor, as attempting to open that results in the same traceback.

Expected behavior:

The character editor or ESI manager open successfully.

Actual behavior:

The character editor and ESI manager fail to open due to the above error.

Detailed steps to reproduce:

I simply came to github, downloaded the latest stable release, and installed it. I have also tried with v2.55.0dev1 and get the same error.

Fits involved in EFT format (Edit > To Clipboard > EFT):

No fit is required to reproduce

Release or development git branch? Please note the release version or commit hash:
