It seems that your system has some problem with the MIT-SHM (MIT Shared Memory Extension) X11 extension. You may need to disable this X11 extensions to use Qt applications, such as Slicer. See for example this page for details.

Let us know if this launches Slicer correctly on your system:

export QT_X11_NO_MITSHM=1
./Slicer

# export QT_X11_NO_MITSHM=1
# export QT_DEBUG_PLUGINS=1
[root@fchredhattst01 Slicer-5.6.2-linux-amd64]# ls
bin  include  lib  libexec  resources  share  Slicer
[root@fchredhattst01 Slicer-5.6.2-linux-amd64]# ./Slicer

It seems that you have run into this issue: Crash on Fedora 33 due to OpenSSL/Kerberos incompatibility · Issue #5663 · Slicer/Slicer · GitHub

Please follow the suggestions described on that page and let us know what solution ended up working for you.

You probably don’t need QT_DEBUG_PLUGINS=1. You can remove it to avoid noise.
