hi, recently i downloaded, for the first time, vic's modern warfare mod in my minecraft java edition (windows 10). I followed every step described by online guides; forge is setted up and works properly, forge profile too. but the problem manifests while, once spawned in the world and opened the creative menu, trying to select the mods window. the game close itself and this message appears on the screen. i do not have installed any other mods. P.S without trying to access the mods window, the game runs properly. what can i do? thx in advance The game crashed whilst rendering item Error: java.lang.IllegalStateException: Not building!
