OK, i got it fixed. I updated Electron.

This is still not working for me. And I am not using a beta version, just the usual Xcode 15.0.1

I had to remove and newly add the VPN connection in the MacOS settings. After that with the 2nd try to connect it works. Mysterious. (Cisco IPsec to a Lancom Router)

That was it for me, too. A restart of the Mac resolved the issue. Thanks.
