rtx-remix [Runtime Bug]: Unreal Gold/UT99 Freezing

Describe the bug

I'm having an issue with both Unreal Gold 226 and UT99 GOTY v436. Both games are set up properly with the runtime and proper drivers, but upon launching they take over 2 minutes to initialize. At this point all I get is audio for the next 10 minutes or so until video finally appears. Only a handful of frames are rendered at a time before another massive freeze happens. Unreal Tournament GOTY with Old Unreal's v469d patch works perfectly with RTX Remix, so this really has me confused. I'm including a screenshot of Task Manager while Unreal Gold is attempting to run.
