App deleted on my PC

Sorry for my “poor” English.
I have been using Bitwarden since (…) years, on my PC (Win 10) and Android… For me the free version is enough. This is a great tool. Thanks.
Yesterday it was impossible to open Bitwarden. After checking, the installation folder (/Program Files/Bitwarden) was empty. I could, however, access my vault through my Android.
What happened? Any idea?
Thank in advance.

There is something funky going on with some machines using the latest Bitwarden installer. Please direct any further questions or comment to this thread:
