The Grammarly tab disappeared

1. Close Word.
2. Press Win+R
3. Copy and paste %LOCALAPPDATA%\Grammarly\Grammarly for Microsoft Office Suite into the search line. This will open the Grammarly folder on your PC. Navigate to the folder with the latest Grammarly version.
4. There should be a folder with a name similar to B788D630FFA4301BCC50E5A81D7BE34; please open it.
5. Right click on EnableGrammarly.exe and select Run as administrator.
6. Press Open Grammarly.

If the Grammarly tab still doesn't appear, please try the following:
