I would suggest supplying IronCefSubprocess log and cef.log to Iron Software support as well.

Here is the general advice for this kind of issue:

Are you running this from a docker file?
Can you try to set up your environment such that IronCefSubprocess has executable permissions? This is different than write permissions.

This line indicates we were unable to set executable permissions for you:

Executing command 'chmod 755 IronCefSubprocess' in '/app/runtimes/linux-x64/native'
chmod: changing permissions of 'IronCefSubprocess': Operation not permitted

You will need to set-up your dockerfile or environment to ensure you have executable permissions for the subprocess executable. This executable is typically located in a path such as bin/Debug/netcoreapp3.1/runtimes/linux-x64/native/IronCefSubprocess

Provided that your environment/dockerfile is set-up properly, you may also set Installation.LinuxAndDockerDependenciesAutoConfig=false;

If you provide the other log files (subprocess log and cef.log), it should further help Iron Software understand why the subprocess is crashing or otherwise not working.
