Natron crashes when I open a certain save

[RaminRAY201]

I have a save that is a bit heavy, but it used to open normally, then one time I put the timeline on a certain frame, which crashed the program, then after opening it worked for a bit then crashed after choosing another frame, but since I saved just before moving to that other frame, now it crashes as soon as I open it, because apparently that first frame started crashing again, and I can't access the file now

I am using Natron version 2.4 release, on windows 10
