It’s not possible to open the Bitwarden Desktop app? OK, since you do not seem to be concerned about what this mystery app is installed on your computer but that you cannot open, then I will not worry about it, either. I would suggest that you go to 
Win > 
> Apps > Installed Apps. From there, find the “Bitwarden” app in the list, and click on the ⋯ (“More Options”) button, then select Uninstall.
After you have you have uninstalled the mystery app (confirm that it no longer appears in the Installed Apps list), please click this link (also available as a link labeled “Standard Installer – Bitwarden-Installer.exe” on the official Bitwarden Downloads page). After you have downloaded the installer file (Bitwarden-Installer-2025.11.1.exe), double-click it and follow all prompts to complete the installation.
When you have completed the above, please confirm that it is now possible for you to actually open the Bitwarden Desktop app that you just installed.
The earliest versions had version numbers like 0.0.1 or 1.0.0 — never anything like “1.0.0.1”…
