Unity project freezes on startup after v74 and OpenXR plugin update

Hello, recently we tried to switch from using the Oculus Plugin to the newly recommended OpenXR plugin. And since v74 (we also tried v76) the game just freezes on startup and gets stuck. The game is working okay in the editor, we are just unable to pinpoint the problem that might be leading to the freezing issue on quest, is there any way to debug the problem? Thanks
