Please help i think i broke my Blender

I am new to Blender and i watched Guru making a donut tutorial but when i copied my donut half way to the build and put it into a folder i cant go to edit mode anymore. Please help.

What :question: Did you mean saved the blend file? And you can’t toggle between object mode and edit mode via TAB or use the GUI to select any other mode (sculpt ,weigth, paint) ?
