3ds Max not responding after importing files

I recently returned to using 3ds Max after long time and I came across a difficult problem. Every file bigger that 2 MB makes the program not responding, meanwhile trying the same files in Blender makes no problems at all. I tried .stl and .fbx files because I have the most of these. I was using 3ds Max 2016 and 2023 version but I encountered the same problem in both of them. I'm slowly getting insane. I would be very grateful if someone would help me find the solution.
