WebDeviceInputSystem._pointerCancelEvent Uncaught TypeError: Cannot set property '2' of undefined

Our project with babylonjs is Published, but sometimes user’s Chrome for Android reports error: Uncaught TypeError: Cannot set property ‘2’ of undefined.
This is where the error occurs:

Maybe, this._inputs[DeviceType.Touch][deviceSlot] sometimes is undefined.
I can’t reproduce this error on my mobile, could you help me?
The babylonjs version is 5.9.0, thanks!

pinging @PolygonalSun

Hey @pink_blue, by any chance, did any of the users who found this provide any kind of repro steps or any more information that we could use to figure out what’s going on?
