1Password can't be started or uninstalled after In-App Update

Dear Community,

i updated my 1Password App about a week ago over the app-update.
I did this successfuly many times before, but now the App won't start if i click it.
The App cannot be uninstalled either and i also cannot just run a new Installer.exe.
Everything is just not reacting anymore.

The only thing that is working is the 1Password Extension in Chrome.
I am running Windows 11 on a Samsung Notebook.

Does anyone has an idea how to fix this?

Thank you guys.
Alex
