linux-hardened kernel with pcre2 10.43-1 - no login (blackscreen)

Please consider opening an issue on the Arch gitlab instance for the bug in pcre2.

I think the electron bug could be https://github.com/electron/electron/issues/41214 Can you start electron under gdb?

Coredump entry has no core attached (neither internally in the journal nor externally on disk).

Probably related to this one - https://github.com/electron/electron/issues/32760

Is it not more upstream?

file /usr/bin/element-desktop

Is most likely a shell script running the actual binary (/usr/lib/electron29/electron), you'd have to inject gdb there.
