Crash report

SUMMARY
Working on a project and it was saving like normal. Kept editing and saved again, program crashed. I re-opened kdenlive and recovered the autosaved file. Deleted extra clips I wasn't using at the moment but had in the timeline. Cleaned the project to delete unnecessary video files. Saved again, and it crashed again.

STEPS TO REPRODUCE
1. Add over 20 videos to project bin
2. Put parts of clips into 4-tracked Timeline with some dissolve transitions
3. Save

OBSERVED RESULT
Crashing.

EXPECTED RESULT
To not crash?

SOFTWARE/OS VERSIONS
macOS: 15.6.1 (24G90)

ADDITIONAL INFORMATION
I tried to understand how to backtrace by installing Xcode and doing something with 'lldb'(?) but it's beyond me, my apologies. I've attached the crash report my computer provided by copy-pasting it to a Word docx. I think it has something to do with 'kernels'? Please let me know if there's any other information you need!!!

Kdenlive is back to working - literally didn't do anything different IDK - can't delete this myself so please feel free to trash this report! I'm sorry for any aggravation I've caused.
