Hi. Sorry for the belated response.

This most likely means that ghci process crashed for one reason or another. More information is probably available in the dev. console (View → Developer → Toggle Developer Tools → Console). If it's a cabal/stack project, the first thing to do is to try to build it and fix any "external" errors that show up (i.e. those that aren't directly in the project code) -- there's a decent chance something like a dependency is missing, and automatics can't handle it.

So, either that, or you've just ran into a particular race condition that occurs when you rapidly open and then close the REPL window -- which is not really a bug as far as I'm concerned, tbh, since everything actually works as expected except a pesky error message.

If it's neither, and you could provide some reproduction instructions, that would be great. Thanks in advance.
