New OBS iteration won't initialize

[Joyful]

I just upgraded--should have left well enough alone as it was working fine before. When I try to start OBS, I get the following message:
"Failed to initialize video: Required graphics API functionality not found. Your GPU may not be supported."

I'm running Windows 10, Version 22H2 (O BUILD 19045.3570)

Anyone know how I can find the old version?

before you do that, provide your newest obs log file from %appdata%\obs-studio\logs
