I was working normally, I left the computer alone for a while when I returned and tried to use the orbit tool it simply didn’t work, I tried restating Unity, but that didn’t work, I’ve completely lost access to it. When I press Alt the move tool is activated instead of the orbit tool.
I opened another project with the same Unity version (2018.3.0b4) but on the other project it works fine, so looks like something on my project went corrupted.
