Recently I've stumbled upon an issue that makes my behavior packs virtually unaccessible. Whenever I try downloading an add-on of mine, the resource pack appears just fine; however, the behavior one doesn't seem to be found anywhere within the behavior section of the world.
At first I believed this was an issue with the new UI not displaying the pack properly; but as it turns out, it's much deeper than that.
To confirm my doubts, I tried applying a resource pack that had a corresponding dependency UUID connected to the bugged behavior pack; and just like I feared, the game fails to recognize it at all and doesn't let me apply the resource pack either.
Instead it just gives me an unknown error screen, that of which I have never seen in all of the years that I've been playing this game.
Just to be sure, I double-checked by going to both the game's archive section and the actual file directory, and the packs are all there downloaded and recognized. The game also tells me that the packs have been imported successfully whenever I import them, so I genuinely got no clue as to what might be causing this.
I've tried everything. I deleted the packs and redownloaded them, I made brand new ones, changed the title in the manifest file thinking there were some unsupported characters: nothing seems to be working. I even deleted the game and reinstalled it from scratch to then import back the whole com.mojang folder, but to no avail. As a last ditch effort, I deleted all of the behavior packs inside of the game's folder, but still nothing.
This is probably more of a corruption issue instead a bug within the game per se, but nonetheless this has been bugging me for a few days and I can't progress my development any further if I don't soon find I a fix.
I'm an add-on developer that runs a small server hosted on my PC, so this is extremely detrimental for me and my community. If anyone could provide me with possible solutions, that’d be much appreciated.
I really don't have any steps I could provide to reproduce this issue, as it seems like I'm pretty much the only person that is experiencing it for no reason at all.
Below this text I have linked an image of the error screen, along with one of the many packs afflicted by this “corruption”.
(P.S: my personal theory is that this has something to do with the scripting version of the pack, as even my previous add-ons that worked just fine don't appear when I redownload them. There also hasn't been any game patch that could be causing this, as this error occured out of the blue while the game was working just fine AFTER I had already updated it. To support this theory even more, I tried downloading a behavior pack that uses the beta scripting API and it works just fine.)
Still waiting for a response.
