When converting my project to 4.12 from 4.11, I of course updated the plugins that I’ve been using for the project, and whenever I launch it, I get the following error:

This is from the log of course. It does show an error dialogue box but it says the same thing, this just has more detail. Oddly enough, this problem only surfaces on the Github branch that I’m compiling from source, but if I launch with the exact same plugins in the 4.12 binary release on the launcher, it works perfectly and has no errors whatsoever. The only information I’ve been able to find on this exact issue has inconclusive answers and were relatively old. If there’s anything I can do to get this working, that would be very helpful.
