One solution for error code 0xCOO70643 is updating drivers on devices with outdated ones, which may help resolve some conflicts in Windows.
You should also try running System Restore from Safe Mode as well as removing anti-virus software temporarily so that the problem does not come from these sources (although they’re unlikely).

Another option is restoring from a backup if available, but this involves taking out older programs and apps before reinstalling everything again afterward which may have an effect on certain programs.
