Crash on start of Skype flatpak due to segfault in libc-2.31.so

[g3blv]

I get the following issue when starting Skype flatpak on Fedora 33.

kernel: skypeforlinux[247455]: segfault at 0 ip 00007f976964ea5e sp 00007f974bffe008 error 4 in libc-2.31.so[7f9769514000+150000]

and

 systemd-coredump[247535]: [🡕] Process 247411 (skypeforlinux) of user 1000 dumped core.

Using latest version of Skype flatpak and Fedora system up to date.

Please let me know if any further information is needed.

Possible I have similar bug on Debian 11 with latest Skype (Flatpak)

[chris-stones]

same bug now, for years for me.
all other flatpak apps run fine.

Since last week I have a very similar experience on Fedora 40. The stack trace looks pretty similar to the one posted by @chris-stones hence me posting here. Not sure what changed as Skype did work for me without (many) issues before.
