Apparently brewsky - the dev - had issues with something. I know it because I did a quick google research and it gave me this result. I’m not a dev, nor an user of his extension, can’t tell you what it was. paul.mcalenan gave you the specific link to his issue.
Also found the Git page, last update is from last novembre. no wonder why it has issues with SU 2023.
Right now you’re having an issue with an extension, but you’re posting it in neither the “official” extension topic, nor the “extension” category of the forum. You might get actual answers and support by posting a link to your message (or the whole gobbledeegook) on the appropriate thread.
