Vault does not reveal

I have Cryptomator 1.12.4 installed on latest stable 24.05 NixOS.
I have made a test vault and when I type password and select Reveal it does not reveal.
In terminal is shows:

13:13:44.800 [JavaFX Application Thread] INFO  o.c.ui.unlock.UnlockWorkflow - Unlock of 'test' succeeded.
13:13:45.137 [JavaFX Application Thread] INFO  o.cryptomator.ui.common.VaultService - Revealed test

After I select Reveal in Cryptomator GUI I see a bouncing folder icon for a short time but vault never actually reveals.
I have also installed Fuse and OpenJDK in NixOS.
Please help!

Cryptomator uses the JavaFX Framework to open a file path in a file manager. In order to work, your system must have installed and allow access to the commands which and xdg-open. (Source: github repo of javafx)
