Hello,
The following might resolve the issue:
- Please make sure the timezone (date and time) is accurate on your system.
- If you’re using a VPN, please disable it.
- If you’re using an antivirus software, try to relaunch the Tor Browser after disabling it.
- If the Browser was working before and is not working now, your system may have been hibernating. A reboot, in that case, will solve the issue.
- Try to uninstall and reinstall the Tor Browser. Detailed instructions to properly uninstall the Tor Browser can be found here: UNINSTALLING | Tor Project | Tor Browser Manual
Then, make sure to download it from here: Tor Project | Download - Another common reason for that error is if you have non-ASCII characters in your username, so the path to tor.exe is something like C:\Users\UserNameWithCyrillic\Desktop\TorBrowser. Then a solution is to make a directory in, say, C:\ for Tor Browser that your user has full access and permission for.
- Please try updating the operating system.
