I updated Vegas 18 to build 527. Then I loaded a project I completed a month ago for experimentation. Everything seemed fine except I was not seeing much (any) GPU action (ASUS TUF RTX3080oc). When I clicked to open my external monitor Vegas crashed. Vegas will not open again. I tried re-loading the software update, but it starts to open and then stops. I tried a previous version and was told I have to delete the new before installing the older version. I uninstalled. Then tried to install and it would not (it asks if I would like Vegas to make changes to my device. I click yes. It says extracting files, then all messages go away and nothing else happens).

I have a copy of Vegas 17 & 15 on my computer, so I tried opening and neither of them will open either. Please help!
