force a crash by pressing f3+c for 10 seconds while in game, and attach it

"/save all" is not a vanilla Minecraft command. This should be reported to the developer of the plugin this command is from.

Ok, I attached a client crash report while logged into affected server.

Marshall Mohror it is vallina, only servers can use it

What are you doing over RCON?

I'm getting this issue on my server. I have not seen it before but it is very much present in 15w47c:

this is also present in 1.9.2, or at least something that looks like it:

Is this still an issue in the most recent versions (currently that is 1.13.2, or the latest snapshot 19w12a) of Minecraft?
