XR threw an exception Type Error on Desktop

Hallo all,
I have developed some 8th wall experiences before and started a new one just now. Doing that I stumbled upon an error I cannot explain and also discovered that it appears on my already published experiences. It seems it only appears when opening the experience in Desktop Browser (what is something that makes also problems that I did not have while working on earlier experiences but that is another topic maybe). On Phone I did not have the errors yet.
I am on Pro Plan and using self hosted.
Does someone have an idea or a hint whats wrong?
That are the errors:

Hi @Lu_Ko - are you able to reliably reproduce the issue? If so, are you able to share a link to the published experience so we can take a look in more detail?

Thanks @Evan , not reliably every time but like 50% of times I try it. I will send you a link via pm.

Btw it is also happening in your examples when running on desktop, discovered in this one: https://playground.8thwall.app/swap-camera-mrcs/
I tested it with device simulation from the developer tools of chrome browser.
