Error with mods

I downloaded a few mods and then i started getting this

Error Uncaught error. Please report this to support@greenheartgames.com: Uncaught TypeError: Cannot read property ‘isCustom’ of null (file:///D:/Program%20Files%20(x86)/Steam/steamapps/common/Game%20Dev%20Tycoon/compressed/codeNw.js:412) Please restart the game.

Enabled Mods: [“gdt-modAPI”,“CheatMod-kristof1104”,“UltimateLib”,“CAMELOT-EXP-PACK”,“CK-percentager”]

i turned off every mod and it still happend. i then deleted the compressed folder and then had it re-download it.

no idea what to do except for deleting the whole game and re downloading.

you have to take this problem of the mod to the Mod Developer it-self. Before you go to the Mod Developers being Kristof etc you have to cut it down to what whats are possibly conflicting with eachother, or the problem could be an out of date UltimateLib or a Save Game that was previously loaded with mods that are no longer there.

its happening without mods too.

i keep getting this. this is a fresh install with every mod removed.

i cant make games, hell i cant even hit the exit button. i have to alt tab and close.

are you playing in a save that you had some mods on it?
try re instal it
