Appimage application not working almalinux 8.6 or 9

Hello there,
While trying to use appimage alone or through “gearlever”, none of said appimage opens or seems to work.
So far on both my machines (the one in v8.6 and the other in v9) I cannot manage to make it work … did any of you manage to be successful ?

Make sure the image is executable.

Hi Joe,
It is already done but still not working, within terminal I have an error :

Error loading Python lib ‘/tmp/.mount_activi4krdYY/’: dlopen: /lib64/ version `GLIBC_2.29’ not found (required by /tmp/.mount_activi4krdYY/

My system is up to date and I have installed GLIBC_2.29 … but it appears that it is not …

I wonder if I have installed it correctly, when I check the version of glibc it is 2.26, which prefix should I use when I install it ?
