Normally for difficult issues, I uninstall a program, restart and then run the registry cleaner app.
This can be helpful since sometimes some of the background operations may be running if you don’t restart.
This is not a fix all but can work in some situations.
Most likely in Safe Mode, the higher level graphics are not going to work.
if you uninstall/reinstall, you should get the project window on first launch, if everything uninstalled completely.
If you have some residual from a previous installation, the launcher may still be using some preference file from previous settings.
Yeah had a feeling the graphics may not be sufficient in Safe Mode.
It would seem from Support that importing large packages can cause problems sometimes. The package I tried to import was over 650 meg compressed. So stopping Unity during this process has really screwed it up!
Would be nice to decompress some packages outside of Unity and bring them in as assets
And it now works! The old project was the cause it would seem.
