Terminal editor not working

[dd-pardal]

OS: Windows 10 20H2

Terminal output (example for "Your first commit", can happen on other levels too):

$ git add .; git commit
warning: LF will be replaced by CRLF in glass.
The file will have its original line endings in your working directory
Can't call method "send" on an undefined value at /c/Users/user/AppData/Roaming/Oh My Git/tmp/fake-editor line 14.
error: There was a problem with the editor '~/fake-editor'. Please supply the message using either -m or -F option.

Restarting the game doesn't solve the issue, but rebooting the computer does.
