3CX Desktop App start not anymore at Terminal Servers

[jonas@ttm]

Not sure if this is related to the latest Microsoft Updates on our Terminalserver (Windows Server 2019) last Weekend or if this is related to the installation of the updates on the 3CX PBX, but since updating the two systems we have Problems with the 3CX Desktop App Version:18.11.1213 (but same Problem also affects 3CX Desktop Version 18.10.461) (our actual PBX Version is 18.0 Update 6 (Build 908).

Since them the 3CX Desktop App ist not loading anymore at the users end and only shows the hanging 3CX logo at startup.
Also a clean re-installation of the 3CX App did not solve the issue.
Maybe related to this, the main log in the Desktop App shows the following error in relation to the electron framework:
[2023-02-01 10:28:59.232] [error] (uncaught-error-hook) {
message: 'Error: UNKNOWN: unknown error, fsync\n' +

' at Subscriber._next (webpack://3CXDesktopApp/./node_modules/rxjs/dist/cjs/internal/Subscriber.js?:80:26)',
type: 'generic'

Ist there know something about that Microsoft did change something in the updates for Windows Server, which causes problems with the frameworks which are using by the 3CX Desktop APP or are there any issues in the 3CX Desktop App in relation to the electron framework or problems between the 3CX Desktop App and the new 3CX PBX Build?



Thanks a lot in Advance!

Regards Jonas.

Hi Jonas,

While we are not currently aware of anything in that regard, a general interpretation of the log points towards the app not being able to write in the AppData folder.

You would get a similar behavior if the app suddenly finds itself in a "read only" environment or has some rights revoked.

This would be a good starting point to check.

Edit: that would also include any antivirus software running on the server that filters our app
