macOS Mail app keeps crashing

In the past couple of months my Macos (10.12.4 and the previous version) keeps locking up and crashing randomly. Apple support has been working it but hasn't found the problem. Any ideas?

These messages seem to be in the log right before it crashes each time:

com.apple.xpc.launchd[1]: Unknown key for integer: _DirtyJetsamMemoryLimit ]

GoogleSoftwareUpdateAgent

com.apple.usbmuxd[1243]: notice & com.apple.usbmuxd[1243]:

"com.apple.MobileAsset.LinguisticData.new-asset-installed"

MacBook Pro (15-inch Early 2011), macOS Sierra (10.12)

I downloaded and installed Sierra on Friday, March 31/17.

Ever since, my Mail app does not work...it keeps crashing after about 3 seconds.

I've rebooted in safe mode,tried reinstalling Sierra OS...same problem.

I've also contacted Apple support and my internet provider, each has NO IDEA what's going on and blame each other for the issue.

Not very encouraging.
