Unity 2020.3.11 with OpenXR : Process that blocks editor loadings

Hi everyone

So we are currently working on a project with several computers running Unity 2020.3.11 on Windows.
When we started working on the PC version and added OpenXR we started noticing infinite loading times (every computer have the issue).

The loadings were saying: "Application.executeMenuItem" (if we save a scene), "ProjectBrowser.OnGUI.ExecuteCommand" (if we duplicate an asset) or "Application.enterPlayMode" (if we enter play mode).

To unlock the loading, we are to open the Process Manager, find the Unity process, open the subprocesses and kill the one who is responding (not the one who is unresponding).

When we do that, the popup say "Application.reload" and the loading restarts and work well.

I don't know if the issue comes from OpenXR or is a Unity Editor bug that's coming when OpenXR is installed in the project. It can also be unrelated (since we use OpenXR for PC versions, and we were working with Android)

Is that a known issue?
Do you have an idea how to prevent this from happening?

We also have long "Refresh Asset Database" time when we open Unity (up to 10 minutes), and we can't kill any process during that time.

Best regards,
