Believed cronet from com.Google.GoogleMobile string in screenshots.

Could you upload the full crash report? The report indicates that the problem took place on thread 5 but the thread is not visible on the screenshots.

It looks that the app requested some time to finish an operation when it was moved to background but couldn't finish the work within the allocated time. As the result, the app was killed by iOS.

This may help

Google.app?  That's GSA, not Chrome for iOS, isn't it?

This indeed looks like iGSA.

The com.Google.GoogleMobile is indeed Google App, which is using Chromium Network stack internally, but it is not using Chromium bug tracker, so there isn't anything that we can do on this side. 

You can use Settings -> Feedback menu inside of the Google.app to describe an issue or share your ideas, and optionally include system logs with more information.
