I used mu Fusion 360 yesterday, and it worked finr.
Shut it down the way I use to, and everything seemed OK.
This morning, I should start it and nothing happend, except multiple message boxes appeared.
"Code can not be executed because, "Qt6Widgets.dll", "Qt6Gui.dll" "Qt6Core.dll" and "CFDatasolver.dll" could not be found"
(Translatad from Norwegian).
I tried to reinstall it, but got the message that "multiple instanses is running".
Restarted the PC and tried again, the same message appears.
Tried to uninstall Fusion, and got the same message.
