Error when running scide built from source on Ubuntu 24.04

I’ve followed the instructions on github wiki and when I try to run scide I get the error:

[4861:4861:0116/085116.590852:FATAL:credentials.cc(125)] Check failed: . : Permission denied (13)

I’ve run it through gdb and got this backtrace:

Thread 1 "scide" received signal SIGTRAP, Trace/breakpoint trap.

Does anyone have any idea of what is wrong? It used to run perfectly on Ubuntu 22.04 but the update to Ubuntu 24.04 broke it.
Not sure if related , but Steam games also got broken with Ubuntu 24.04 which was fixed with setuid of bwrap, a kind of sandbox/namespace binary.

I’ve tried recompiling it to no avail.

A kind of fix is to run it with:

QTWEBENGINE_DISABLE_SANDBOX=1 /usr/local/bin/scide

But maybe there should be a build flag. Or the problem is in 24.04 and some apparmor configuration for qtwebengine library is needed, if that is even possible.
