Game constantly crashing

While playing, pretty frequently after these last two updates, I get either "connection lost" and am kicked back to menu, or just "Software Crashed" and am kicked out of the entire game to the Switch Home Screen.

 

I have been playing on local, as I have bad internet out here in the woods where I live, so I don't understand what connection is being lost to kick me. It's happened at least 10 times since the last update released.

I haven't tried anything beyond powering off my system. The crashed can happen as often as 3 min apart or 2 hours. I don't have any screen shots, but I can upload some when it inevitably happens again.
