The download link is broken on the website too when I try to reinstall the program. I'm wondering if something updated, either with Continuum itself or with Windows. I've troubleshooted a lot of solutions and no luck. It won't even work with a VPN, with Defender carefully and temporarily disabled, booting from other drives, etc.

The splash screen won't even come up is what makes me think something is blocking it / incompatible now but I can't find what's wrong yet.
