Answer 1

I think this bug because this simulator error with system UI , u can wipe data of simulator then run again

Answer 2

Go to android simulator --> tools --> AVD Manager--> Select the device you are running and wipedata and run it again.

If it not works select another device and try it.

Am not sure, it may the problem in simulator .
