"Start AR" loading failure on some browsers

When using a specific browser, namely the browser in WeChat, if the user does not click “allow camera” fast enough or the project fails to load quickly enough, the loading process fails completely and it displays a page with a button labeled “Start AR” (clicking it does nothing). In the debug messages, it displayed:

â–Ľ [XR] Pause cannot be called at this time.
at Object.wA [as pause] xr-simd-26.0.6.150.js
at (anonymous) xrextras.js?s=1

This shows up precisely at the time of the error. I know this is a special case that only occurs on a specific browser, but I supposed this can’t be unfixable, because it’s another just chromium-based browser. Is there anyway I can fix this? Thank you
