Character & Animation

Been working in Unreal for a bit now, and this is the only project I have had this issue. It is seemingly random, as in I cannot consistently replicate it, but it ONLY happens when I open an Animation Blue Print that I’m working in that uses a few Pointers in it, along with an isValid node (which I figured fixed this issue). Any help would be appreciated… I posted the error log here:

Access violation - code c0000005 (first/second chance not available)
