The problem really needs to be reproducible for sending off to the devs as a bug. Just tried a 7360x4912 jpeg (about 8 Mb file size) > 1080x1080 without a crash.
1) This laptop Linux kubuntu 20.04 Gimp 2.10.30 16 GB memory 500 GB ssd intel i5 intel graphics - using interpolation No-Halo and no crash
2) A Win 10 VM Gimp 2.10.30 a more modest 4 GB memory - using cubic interpolation this time - no crash.
Very easy to blame Gimp but more probably a local problem. Running out of resources. A hardware issue. Some user setting in the User profile.
Always useful to disable the Gimp profile and let Gimp make a default, then see if the problem re-occurs. Same with the image, try a different image (same size and format, although it seems all your large images ?) Open one image only, not multiple. Keep it simple. It is all about ruling out possibilities.
