Browser extension locks the vault very often even though the timeout is not expired

I’m using bitwarden and the browser extension with Chrome. The vault is configured to be locked after a timeout setting and I’m using Windows Hello to unlock the vault with a fingerprint reader.
The vault is locked sporadically withoud exceeding the timeout. This can happing several times in a minute. Really annoying.

Has anybody oberved the same problem and knows how to fix it?
