Hello,
Recently i started getting this error and my Vaultwarden is not working.
I had install it on my homeserver and install it without docker.
Not sure how to help. Looks like the file does not exist.
I would suggest to check how you installed this and see if they have some way to support it.
This project only provides docker container’s, and thus hard for us to support all other deployments.

I would check the /opt/vaultwarden directory and see if the binary is still there. If not, follow those steps again.
