neovim hangs while doing :%s

[eyalk11]

Hi,
This is not conclusive, but when doing :%s with preview on synced file, after pressing enter, neovim was hanged.
It happened 3 times. When I did /gc, it went OK. I don't really see external reason for this..

I was able to replicate this. Neovim hanged when doing :%s/<search>//g. However, when I added a character in the "replace with" place (ej. :%s/<search>/<space>/g everything worked out

I was also able to replicate this on Windows 10, but I have not found a fix so far. When using :%s/<search>/<replace>/g or the /gc option comrade crashes. A connection can only be re-established by restarting PyCharm. Even closing the connection in PyCharm doesn't work.

PyCharm: 2020.3
