Cannot start more than one browser processus since CEF 121

[apique13]

Describe the bug Cannot start more than one browser processus since CEF 121 (https://github.com/cefsharp/CefSharp/issues/4668) I understood it is because of the CefSettings.root_cache_path parameter, but what is the good solution to manage it ? The only workaround possible should be to define a random root_cache_path for each instance, but it is a bit dirty.

To Reproduce Launch run.bat to start the demo browser. Launch it twice, The second browser will hang.

Expected behavior A clear and concise description of what you expected to happen and what happened instead.
