I apologise if this is not helpful but since its what I would call a massive bug (I think) i need to report it
After blender crashed my project I tried to reopen the project again but trying to open the save just crashed blender immediately thought it as a corrupt save so i backtracked to old ones and 50+ saves would not open I eventually opened the saves threw trial and error but Blender for some reason I have no idea why or how deleted my mesh and armature from the outliner I don't know how or why it happened but it no longer existed although it did exist in the scene which is very weird no amount of appending, importing or copy pasting fixed this every time I would try to open the project file it would crash if I tried copy pasting it from one file to another it would crash Its as if there was no data on either object even though I could edit the mesh and armature and make changed as I pleased. its very weird and the biggest bug i have encounter with blender up to now but I just scrapped my project and moved on since i was just learning sorry if this is of no help to you and your development team.
thank you for your continued development of such an awesome software ;3
Exact steps for others to reproduce the error Sorry im not sure how it happened in the first place
Based on the default startup or an attached .blend file (as simple as possible). sorry I also deleted the entire project
