I'm not sure how effective disable-user-extensions is as we have found in other bug reports that buggy extensions can just ignore the disable setting. Extensions need to be uninstalled to be sure.
It is also possible you have disabled extensions successfully and the latest crash dump (bug 1859890) was just sitting on disk from before that time. Hence removing extensions may have successfully stopped the crash from occurring. Let's give it time and see if any more occur.
Also worth noting you are the only person reporting this crash right now, which suggests it's caused by something uncommon.
The GSettingsChange s.txt in this bug and bug 1859890 both say you had at the time of the crashes:
b'org.gnome.shell' b'enabled- extensions' b"['<email address hidden>', '<email address hidden>', '<email address hidden>', '<email address hidden>', '<email address hidden>']"
