So this could be helpful for developers i think. Maybe some users can check and confirm. But i am sure the problem is caused by the Edge-Extension. I checked on two other computers and could reproduce this issue on both. Crashing with activated Edge-Extension and stable running without the Extension.
Im am also facing the same issue. In my case i found a solution. I disabled the "extension for MS Edge" in the settings of the Edge Browser and Enpass is running without crashing with Firefox and Chrome extensions. I know this is not an option for all users but it is worth to try.
