Same thing here,

I'm using Unity 6000.3.7f1 and standalone Meta XR Simulator 83.02.0.14, with an AMD RX 6600.

Please let me know if you find any solution.

You have exactly same prob and environment with me! It always shuts down right after mounted with unity

Excuse my french, but what kind of suggestion is that second half supposed to be? Seems more like an AD than anything helpful.

Regardless still seeing this with 85.0.0 on both SDK and XR Simulator version with Unity 6.4. First run with Simulator works fine, any subsequent run full crashes the editor.
