Additional notes
Add any other notes about the problem here.
im using v2.0.1 because for some reason v2.0.3 will only run in terminal, and im not using hammer++. idk why it wont run.

oh, just to note, i get the same error for both Construct and my own map

[kowhaifan]

turns out my problem for that was that my .bsp to .vmf converter wasnt working properly, fixed it but now i get a new error:

i tried 2.0.3 and 2.0.2 on another computer, still didnt work there either, and i got the exact same error when trying to convert my VMF.

[kowhaifan]

oh also literally no version other than 2.0.1 will run via GUI on either computer, they work using terminal (though i really dont want to have to specifiy every single directory VPK in a command)

[randomguyorsomething]

same issue, different error (i may be stupid)

SEVERE: Error while loading vpk file: Invalid signature

idk what vpk files to import 😭
