INVALID_SOFTWARE_INTERRUPT usually points to low level software behaving badly most often a buggy or outdated driver security software hooking too deep into the system or firmware that does not play nice with recent Windows 11 updates. I also see it triggered by corrupted system files after a forced shutdown or failed update.

Safest fixes are to boot into Safe Mode uninstall recent drivers or third party antivirus run Windows Update fully then run sfc and DISM to repair system files and reset BIOS settings to default if anything was tweaked.

If the PC keeps crashing or will not boot stop trying random fixes and focus on your data first by pulling the drive and connecting it to another PC or using a trusted recovery tool like Stellar data recovery software from a bootable environment so you are not stressing the disk further before doing a repair install or clean reset.
