Export as OBJ completely changes and breaks any model/mesh i export

anyone else have this?

exporting anything as obj completely messes up the model

how its meant to look: (pre export as obj)


how it looks:

this is not exclusive to this one model
i tried exporting simple parts and the same happened

this is not a blender issue, since if i just export the model as obj, then import it with no outside interference it still happens

idk how long this has been happening but i noticed it yesterday
i dont have any beta features that mess with exporting/meshes enabled

another example of the same exact model being exported a 2nd time, and having completely different- but still broken -results
