follow-up: i have discovered that just switching to a different network, and then back, works around the issue for me. i don't even have to switch the other device and pair while on the other network. does anyone know if there's a way to do this network "reset" without actually switching between wi-fi networks? turning wi-fi on and off doesn't actually help—only connecting to a different network and back again.

if you are using a file that you know should work, it might be the web server not serving up usdz files correctly (with the right mime-type)? is it possible to share the URL to the webpage?

holy carp, juyoungk23's solution (switching to a different network, pairing, then switching back) is the only thing that works for me. thanks for suggesting that. please apple, fix xcode.

i am so tired of having to reboot my vision pro AND my macbook almost DAILY just to get xcode and the AVP to talk to each other again and again and again.

i followed @instantinteractive's suggestion but slightly differently: deleted /Library/Developer/PrivateFrameworks installed Xcode.app/Contents/Resources/Packages/XcodeSystemResources.pkg on my system at least, XcodeSystemResources.pkg creates the /Library/Developer/PrivateFrameworks folder. anyway that fixed "Toggle Appearance" in the Simulator for me! thanks for the tip!

Tried this on two different computers, too. Still nothing. I filed a Feedback fwiw.

Same thing is happening to me. Did anyone figure this out?
