Hi everyone, I'm trying to generate a CRUD page inside ABP Suite, however I seem to be getting the following error instantly

My suite, studio, cli is all up to date, as are my packages, everything is building. As far as I can tell, there is nothing fundamental about the project I've changed with regards to config. I did switch to central package management a month or so ago, but it's been fine generating entities in between then and now. I noticed this issue when I tried to create a new entity through the suite, after finding it didn't work, I tried to trim it down to a simple form (just one string property) and that still didn't work. And then I tried to edit an existing entity just to test it, that didn't work, and then I tried to save an entity I haven't made a change to. Which also didn't work. I just get this error every time.
I also tried upgrading to preview versions, and downgrading to previous versions, but it's the same error every time.
I can share logs, or entities if needs be.
ABP Suite seems to be failing to generate entities correctly. I can't find anyone else experiencing this problem looking at previous support tickets.
From what I can see, there is nothing mentioned in the logs even after setting suite logging verbosity to verbose. I am unsure of *exact *reproduction steps, but this has happened on 3 individual projects (I can share each json file if you want)
After a certain amount of entities created, it gets to a point where it generates malformed entities.
Here is an example of what is generated in MyEntity.extended.cs, with basic string properties "TestOne", "TestTwo", and "TestThree"
public MyEntity(Guid id, )
: base(id, )
{
}
This is invalid code that of course will not compile. It seems to be failing to add properties of my entity in several places, like the base entity, extended entity, tests, as well as create and update methods and Dto's in the backend. It should look like
public MyEntity(Guid id, string testOne, string testTwo, string testThree)
: base(id, testOne, testTwo, testThree)
{
}
I have tried versions 8.1.3 (where I first noticed the issue), 8.1.4, and 8.2.0-rc5. I've also tried changing generation options like turning off crud page generation, turning off custom code, disabling backend etc and it didn't seem to make a difference. Tried Blazor Server, WASM, and Web App. Also tried clearing my Nuget cache in case it was resolving wrong package versions etc.
All 3 of the projects I've tested on have been more or less stock. The only other changes I've made have been to add some modules, and tweak some templates adding some more hooks in them etc.
