GBoard on Honor 200 Pro

Does someone other recognize that GBoard closed itself, when you tap on bottom side on the display (with gesture navigation)? Especially on the right side. There is no crash notification. Is there a fix or a workaround?

It's really annoying because on research the text you had write is deleted. It seems that it only happens when you use GBoard. SwiftKey and another random keyboard from Playstore seems to be okay.

Please no discussion why or why not to use GBoard.
