I keep getting the attached error when trying to update to the newest version of Anki. I was prompted to update the software upon opening, but now I can’t even get into the app. Any help would be very much appreciated.
Restarting your PC might fix it and allow to install a new Anki version.
Otherwise, maybe use Sysinternals Process Explorer to identify the process and close it. After that, delete C:\Program Files\Anki with File Explorer or just go ahead and install a new Anki version.
Also disable any extension with Shift when you launch to see if any pre-installed extensions caused this.
