I am totally tearing my hair out over this one. I have a largish VCL project (100+ forms and frames) and recently I have started to reegularly "lose" ALL the <FormType>dfm</FormType> tags in the drpoj file, so when I try to add a frame to a form all I get is an empty frame list.
Re-adding all the FormType tags to the dproj file every week or so is a pain. Before I give up and rebuild the project from scratch, has anyone any idea what is happening with the IDE? I am using Delphi 12.2
