If you modify any generated files:

• Put code only between the comments that say "user code here", and click the checkbox for retain user code: MX > Project Manager > Code Generator > +"Keep User Code When Regenerating"
• Keep your code in a version control system, or at least zip projects and put on a backup device.
• Don't put your code in main.c, Put your code in main2.c (or main2.cpp), and put a call to main2() in main(). When regenerate ensure the init code in main2() is updated to match main(). Few extra steps needed for change to support cpp files.
• Better yet put all your own code in a separate folder (ProjectCode or MyCode, next to Core)
• Create a document to log **all the changes** you do to generated files, so down the road you or others will know how to create similar projects, or recreate this project if it gets corrupted, or a major STM32Cube change occurs and auto update doesn't work.

Develop and modify code in a sandbox, not in a directory/tree that automated tools are likely to overwrite, modify or delete.

Move your code into a sandbox, and use source code management tools to archive/save it
