Hi @Anonymous
Thanks for posting! We are sorry to hear that you have been unable to access Fusion 360.
When you uninstalled and reinstalled Fusion, did you use the clean uninstall utility tool? If you did not, it may be worth trying to use the tool at this link and reinstall Fusion. Also, have you disabled any antivirus and firewall software present on your system to ensure it is not interfering with Fusion?
Also, are you certain that your graphics drivers are up-to-date? You can find your graphics drivers in your computers system information, which can be accessed without opening Fusion. I usually update my graphics drivers twice a year to keep Fusion running well - please confirm that you are on the latest version for your system and update as necessary.
Also, you could try deleting the loginstate.xml file to see if it will resolve this behavior. Please refer to the instructions below to delete this file:
Windows
1. (Close Fusion 360) In windows explorer browse to %localappdata%\autodesk\web services
2. In the Web Services directory, right lick on the LoginState.xml file and select delete
3. Restart Fusion 360
Hopefully this helps! If you are still unable to launch Fusion 360 please gather your log files and attach them to this forum thread - I am happy to have a look! Feel free to let me know if you have any questions.
