I can ensure you that this problem is not a "Ventura" issue, the same issue also exist in MacOS Sonoma.
And it's not related to one specific browser. For me the behaviour is the same regardless if I run Firefox or Chrome. But per normal I am not foreseeing this being ever resolved - and Enpass team will most likely "not able to replicate" and ignore the problem many people are having. I am looking into replacement for this password manager at this point.
Something I found out is that - if i restart my laptop it will work for a while - then it start freezing up again - there are no error messages only nothing happens and if I go to the standalone app and try to "lock" it i am only faced with the spinning wheel.. My guess is that there is a severe bug in how the extension are communicating with the standalone app and it's falling into some unexpected scenario or deadlock.

Can we please get some update that someone in Enpass Team is pulling their hair trying to fix this?
