Unable to log in to self-hosted vault with Bitwarden plugin in Chromium Edge

It seems that the Bitworden plugin is not working correctly with the new MS browser, Chromium Edge.
I run a perfectly working self-hosted vault that i can use with Firefox, android and Google Chrome. Works fine. But it’s only with MS Chromium Edge that i run into this weird login-problem. I run Bitwarden plugin version 1.45 on chromium Edge Version 84.0.522.40. Can anyone shine some light on this? Is there a workaround?
