I think we are all a little confused about your workflow here. Maybe you can help us understand. You said:
"i designed a part in 360 and then exported it to bambu but now i am trying to modify the part but it wont let me convert it back to a solid without all of the faccets"
We are wondering why you are trying to convert from mesh -> solid if you already have a Fusion design that is a solid - this is what you exported to Bambu. Just go back to that original part, edit it, and re-export the edited version.
In general mesh -> solid is an incredibly hard conversion, and you should never use that workflow for anything non-trivial, especially if you already have a solid, native version of the part.
Also, you said: "and it keeps crashing the whole application". Is it an actual crash (do you get the crash reporting dialog)? If so, did you send those reports in? Or, is it that the mesh is so large that whatever operation you are attempting is just taking a very long time to complete, and if you let it go, it might eventually finish. Crashing and being very busy are different states.
