VP 23 freezes when pausing/stopping preview

I upgraded from 22 to 23 last month and am having a very frequent issue with Vegas hanging up when I pause or hit stop until Windows says it needs to close the program. I know when it's about to happen because the preview will start endlessly calculating/loading (ellipses after the frame number) and then freeze altogether once I try to stop playback. Audio will continue to play until I forcefully terminate Vegas. It seems to happen when several FX are being used at once, more specifically when OFX plugins are in the mix; both NewblueFX and Boris Continuum effects can cause it. Both plugins worked fine in VP 22 and they are running their latest versions.

I don't think it's necessarily a media file contributing because so far my project is just several layered PNG's, a GIF, a text generator, and an MP3, but maybe I could be wrong.

Things I've tried so far:

  • Adjusting the preview quality
  • Re-installing VEGAS Pro 23.0 (build 302)
  • Changing Nvidia drivers from Studio to Gaming
  • Enabled hang detection in the internal settings (this proved unhelpful because the crash report shows little happening, other than a breakpoint error in the minidump due to me hitting the terminate button)

Setup:

  • OS: Windows 10 22H2
  • CPU: AMD Ryzen 9 5900X
  • GPU: GeForce RTX 4070 Super

Hardware acceleration is enabled and my GPU is detected by Vegas. Hopefully I'm not forgetting any other details here. Any troubleshooting tips would be super appreciated.

If you bypass all Fx does it still happen? It would be good to narrow down the Fx that are causing an issue (assuming that's the problem).
