I dont know if any of this will be helpful - but a few things to try:
Check the installation folder permissions, or uninstall and try reinstalling into a different folder/drive.
Check Windows Event Logs.
Your running the installer as admin? Try running rack as admin.
Not antivirus related? Using Windows Defender? temp disable it or create an exclusion to be sure.
If you have any 3rd party security software, temp disable those too… to test. Even try killing any un-needed shit in the systray.
Got a usb audio interface? Try disconnecting it then starting rack. I have a similar spec to you and while I’ve never had this issue, my Audient iD14 interface was acting weird for months before i figured out that it was the usb root hub it was hooked into (MSI mobo). Just swapping usb port and cable wasn’t enough in my case.
In fact, try removing any non-essential usb devices, just to be sure.
(this ones a bit of a stretch) I had an issue recently with Waves plugins not loading. That turned out to be a C++ redistributable problem. Rack is based on C right? Maybe theres a dependency that aint working in the same manner so repairing c++ redists via add or remove programs or downloading the lastest installer from ms might do something. (probably not though.)
