Instant crashes on loading screen when loading a save (New and converted worlds)

[raven anvil]

Hi, I've had this issue happen on a couple worlds now and would like to know if it's something I can avoid.

One world was started before the latest unstable branch update. I converted it and it ran fine for the first session. However, after quitting out, the world now instantly crashes the game while on the initial loading screen. I figured this was an issue with conversion and chalked it up as the cost of playing unstable. However, now a new world that I started in the current unstable build (42.14.1) is doing the same thing. It was fine for the first session but now crashes the game on the initial loading screen.

Going out for a while but let me know if there are any files that will help with a diagnostic and I'll get them to you when I'm home. Thank you for doing what you can to help!

EDIT: Just to add, zero mods being used. Completely vanilla.

Can you share your logs.zip file found in %UserProfile%\Zomboid?

Problem seems to have mysteriously fixed itself after starting my PC again (I tried a restart of the game and the PC earlier when the issue first presented itself with no fix)
Still attaching my log in case the issue can be identified for future reference.

This is happening again, restart lets me get into the world but typically I crash within 5-10 seconds of gameplay (After the "CLICK TO START")
