I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

This looks very similar to a series of crashes that were fixed but have not yet been released. The fixes are scheduled to be released soon; can you test when 6.7.0 is out?

[leandromperez]

I will, and I'll keep you posted @morganchen12

Going to close, since the issue is expected to be fixed in the upcoming 6.7.0 release.
