I can reproduce this. From micro's code I see that the Press enter to close message actually indicates that an error occurred. So this message seems misleading, and moreover, it doesn't tell us which error occurred.

I've instrumented the code so it says which error is it:

diff --git a/internal/shell/terminal.go b/internal/shell/terminal.go
index 6fb1ce7f..5712efbd 100644
--- a/internal/shell/terminal.go
+++ b/internal/shell/terminal.go
@@ -2,6 +2,7 @@ package shell

-				Term.Write([]byte("Press enter to close"))
+				Term.Write([]byte(fmt.Sprintf("Press enter to close: %v", err)))
 				screen.Redraw()
 				break
 			}

and I can see the error is:

Press enter to close: read /dev/ptmx: input/output error                                                                                                                                                           

RunTermEmulator() uses the https://github.com/zyedidia/terminal library, which opens /dev/ptmx using the https://github.com/creack/pty library, and reads characters from it. Apparently, when finishing running the fzf job, reading from /dev/ptmx fails with EIO for some reason.

We can try to debug it further.

Quick googling: https://www.google.com/search?q=%2Fdev%2Fptmx+eio
