    I suspect that as with the other issues filed from @BlakeWuh, that it may be very difficult to track this down without a local reproduction. However adding @chunhtai who may be able to interpret these backtraces in the accessibility code.

    @Bestfastfire

    Same here for a long time, it occurs with very few users and it's almost impossible to reproduce, I only got it 2 times and it was completely random
