Mac osx nextcloud 3.6.2

My nextcloud client (3.6.2) doesn’t work on my mac osx 12.6.1. when I double click on the app nothing happen, it doesn’t start any GUI and files (on a webdav server) are not sync.
For sure I made this for 1 day. Now it (the mac client) would not start and files on cloud are not sync.
I think the prob is the nextcloud app. Do someone have the same prob?
