I see. I tried to replicate that with the link cable on a Quest (1). (I had not previously tested this version via QuestLink mode). However, in my test, it did start up and run normally.
Have you experienced similar issues previously with other apps? I found an article, which may have some helpful troubleshooting suggestions:

Beyond these, I am actively working on a native Quest port, which will be available to check out soon.
