I am running latest version of Spine 3.5.46 Professional. Windows 7.
Once it gets to this state I cannot interact with anything and must force close Spine.
I attempted to reinstall but get same problem with attempting to open a new project. When it opens any browse window Spine hard locks up.
Fixed the issue, sort of.
I had to uninstall Spine from my secondary drive and move it onto my C drive. As long as it was on my other drive I was unable to browse to anything but as soon as it was moved onto the C it worked as normal.
