When I open a blueprint after playing a level the editor crashes and if i just restart it the editor crashes every time i try to open a blueprint. If i delete all files from saved, intermediate and binaries and the visual studio solution, i can open blueprints at the start before playing or compiling but if i try to open a blueprint after playing i get the following message:
Access violation - code c0000005 (first/second chance not available)
