I am having the same issue as well on Windows 10. Display of the app is similar to the pictures above and it renders the app unusable. I tried to reinstall the App, rebooted the PC several times, even went through the trouble shooting section and followed instructions under “Enpass is blurry or having visual artifacts on Windows. How to fix?”. Nothing worked.
Note that I have version 18.104.22.168 installed on my Android phone and it is working fine except for some new intermittent issues with fingerprint password not working and no option to put the password manually. This issue is minor as I can resolve it by restarting the App. The issue with the Windows 10 App on the other hand is frustrating as it is unusable.
I hope someone from Enpass is reading this and a workaround is underway.
