Hi there, I have tried all of the recommended fixes, but fusion still doesn't finish loading and stops responding. The task manager crashes and I have to power off. I have uninstalled the antivirus software, for the moment. I have remove the latest windows update. I have tried many attempts to uninstalled /install fusion.

Hi @tony_fortunato1 ,

i see a problem in the attahced log file xerces-ad-c_3.dll is in use

Do you have other autodesk applications in use? if yes

Close all Autodesk applications: The file may be locked by another running process. Ensure all related software, including background services, are closed via the Task Manager.
Restart your computer: A simple restart can often clear the lock on the file.
Use the Fusion Service Utility:
1. Go to the Windows Start menu and type "Add or remove programs".
2. Find Fusion 360, rightclick and select Modify.
3. This will launch the service utility; run the Repair function from there.
If not installed, do a fresh installation

See if this solution works
