Bug#1125777: libmozjs-140-0: Latest binNMU makes gnome-shell crash on arm64

[Sally A.haj]

Hello, I am on RPi5 (Debian Testing), after updating last time, I
couldn't reach GDM3 or GUI in gnome in gerneral. I don't know what the
reason behind that. I have copied my system logs to this link
https://0x0.st/PKb-.txt 
Do you think my issue is related to mozjs or gjs?

Thank you,
