[Runtime Bug]: Crash on start for both Portal and HL2:RTX

Describe the bug

These are for the steam release versions, not any personal meddling. The application opens, whether it be portal or half-life 2. That is it. By opens, I mean the valve brand screen displays, with the Remix blurbs in all their normal spots. That last for about 1-2 seconds. The sound of the valve theme cuts off, and the application freezes. After about 20 seconds of thinking, and my tired clicking, the application closes or the Runtime failure box appears. My drivers have always been the newest possible, but this has been a persistent issue with portal and now HL2.

How do you reproduce the bug?

Fresh download the game and press play, apparently. :)
Those were the only steps taken for HL2

What is the expected behavior?

I've played Portal RTX. Much closer to the game's release, it actually booted, and worked, and I could play levels, and it was fun. Then the next time I tried, and believe me I've scared myself with some things I've tried, it does not open.

Start by comparing bridge32.log, bridge64.log, remix-dxvk.log, and the four NvRemixBridge crash dumps attached to the issue. Reproduce the startup freeze with the Steam Portal or HL2 release and use those artifacts to isolate the runtime failure. Done means the affected game reaches gameplay without the Runtime failure box.
