Symptoms
When launching The Crew Motorfest through Steam, the game fails to start regardless of which Proton version is used. The launch sequence progresses past the Ubisoft Connect launcher successfully, but then a small window appears displaying the message "get pipeline cache". At this point, the game freezes completely and becomes unresponsive.
This issue also occurs on EndeavourOS using both the default kernel and Mesa drivers. The problem has also been documented in this GitHub issue report:
https://github.com/ValveSoftware/Proton/issues/9119
where some users with Intel Arc graphics cards (one user with an ARC A770M) report experiencing the same freeze during the pipeline cache process.
Small note on the side: I'm using the xe Kernel-Driver which is experimental in nature, but the same issue occurs with the i915 driver as well.
