Shotcut crashes when I open an MLT

When I try to open a specific MLT file, Shotcut crashes. My other MLT files don’t crash when I open them. Any possible causes? Any fixes?

Never mind, got the file to open but I had to wait a while.

It sounds like it’s opening the associated clips and you’re looking at a delay as the files are read(can a developer confirm?) if that’s the case faster disc(ssd) would help
