Hello @Ka_Tray,
It is indeed the case, like if you load your profile in newer version, then it cannot be used again in older version. Also if you load the profile with some map DLCs and then if you will try to load back it without that map DLC, it won't load.
So if your friends want to play with you, the newer version and then go back to old version to play some mods, then I recommend making the exact copy of current profile with another name and then he can use one for latest version and other for older version for mods. If you want to know how to make copy of your prolife, you check out this youtube link.
I hope I was able to answer your question. If you have any more doubts, feel free to tag me.
Best regards,
Aashraye
