Fusion does not launch after new installation on MacOS

[dirkRRPMG]

Just downloaded the latest "Fusion Client Downloader" file for MacOS (Monterey v12). Installation goes as planned, but Fusion does not launch after installation. System requirements are OK. Tried all suggested solutions (reboot, disconnect 2nd monitor, Shift+Click, etc.)  ; no luck. Even "Autodesk Fusion Service Utility" app won't work. Only the "Remove Autodesk Fusion" app is working. Did a full removal and a full re-installation, but again no luck.

I'm eager to test the product, but it won't launch. What can I do ??

@dirkRRPMG @If you have the product uninstalled now can you please restart your machine and install it again. If the problem repeats can you cannot launch Fusion service utility , please follow the. Slow article and we would like logs for application logs and the service logs. 

Also, let us know if you have any other Autodesk products installed on this machine.

Hi Rajkumar. Thanks for your feedback. Did again a full uninstall of the product followed by a reboot of the laptop.

Then installed the software again, but without anything connected to the Thunderbolt port (no external devices on this port ; only external HDD on USB). That seemed to be the trick. All works now, even with 2nd monitor, keyboard and mouse connected to Thunderbolt.
