Here is what I’ve done,
Chmod a+x GDevelop*.AppImage
[24284:1023/194143.843095:FATAL:setuid_sandbox_host.cc(157)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I’m aborting now. You need to make sure that /tmp/.mount_GDevelVDvtzt/chrome-sandbox is owned by root and has mode 4755.
