Best password manager in combination with RDM?

ok i'm about to throw bitwarden out the door and switch everything to another password manager.

I have a Remote desktopManger environment for our company with about 40 users.
about 200 customers who all have defined at least 4 servers.
I have all my passwords stored in Bitwarden cloud and linked to the API.

at least 1x every 2 months no one can work anymore because there is something wrong with the Bitwarden connection.
"Unable to retrieve Bitwarden credentials", I can shut down at night and leave everything working, and come in in the morning and nothing works.

then I can send another email to Bitwarden support, the first response is always within 5 minutes and then 10 standard questions are asked, which I answer and it remains silent.

Updating RDM, downgrading, rebuilding Bitward and API nothing helps.
somewhere there must have been a change ( and 99 out of 100 cases not on the RDM side that runs locally ) and my users are dissatisfied.

what would be the best practice?
Run Keepass or Lastpass locally and extract the passwords from it and test it intensively yourself in a test environment during updates?

who has a stable environment?
