I had the most recent version.
For what it's worth, it turns out it was not BepiinEx but a mod manager that got broken from the patch (configuration manager from Nexus) I hadn't considered it an issue because I wasn't running any mods for it to interact with, but as soon as I removed if from BepinEx plugins folder the issue was resolved.

Thanks again all for your help!
