What version of the addon are you using? (Stating 'latest' is not useful)

v9.2.3

Do you have an error log of what happened?

Any additional information? (example: WoW language if not English)

There is nothing in the code that could cause this. Please delete the entire addon and install it fresh, preferably using the CurseForge app to avoid issues.

Doesn't work because it's for 1.13/1.14.

So this Addon doesn't work for Vanilla (1.12)? On GitHub you named the file ErrorMonster_Vanilla.toc. So I tought the Addon is for Vanilla (1.12). But inside it says Interface: 11403 (1.14.3).

So it's a bit misleading. You should rename it to ErrorMonster_Classic.toc. Classic != Vanilla
