Shotcuts keeps Crashing


Hi, I’m working with an mkv with an AVC codec, and Shotcut keeps crashing when I try removing parts of the timeline by separating it into two clips and then removing one of said clips.
The file plays just fine by itself, but if i try keeping only 5mn out of 80mn, it crashes.
Not sure what i can do, since there is no crash log :x


There is an application log that may provide useful information (but not always):

As an experiment, you could try to convert the clip using “Convert to Edit Friendly…”. But an 80min clip will be very large.
