You can save your profile “data” that you need to share between your two projects to either a JSON file like @Monty_Bagati states or to spreadsheets that are located on your hard drive somewhere–all you need is the pathway to where the file, or spreadsheet, is located and name of the file, or spreadsheet. After you run the first project saving the “data” to file, you can run the second project and read the “data” in from the file.
Although I don’t recommend it, you can also write back your new data to your global variable(s). There was a discussion on this forum about doing that and code too on how to do it–I will let you search for the discussion so that you show interest in the idea. However, if you are not wanting to write to files, that is another alternative. Writing to file would be easier and SAFER. You need to persist your changed data between your two projects and that means writing it out to disk.
