CDK Fatal Error

I recently downloaded the War Thunder CDK today to make a map for a cinematic. i opened the location editor which worked fine but i couldnt chage the map, come to find out i have to use the mission editior so i did. once i opened it i selected a map from my AppLocal folder and it crashed, i also tried opening a map through the Steam\Local folder as i thought that was the issue, but i got the same error. the only map that does work is the Britian.bin map which is the map you spawn in normally. i need help badly



same happens for airfields
