Just a quick notice that ther’s already a thread about this with other possible solutions here: Battlefield V Donť remember my settings.
I have disabled One Drive, but i will try it
Hi guys, I have chat with EA Support, they know about this problem and fix will come in next update.
Perhaps setting bfv.exe to run as admin in the properties also will help.
Also, Merged the threads.
I had the same issue in the beta as well. The issue is: Every time I start the game, it feels like, I started it fresh. I have to set the brightness and play the intro through, only after that, I can get into the Main Menu. Sadly the settings (all of them, graphics, controls, gameplay etc.) are also gone, and I have to set them EVERY TIME I start the game. I tried every possible way, that I found on Google, but none of them worked. Disabled Cloud Saving, ran BFV and Origin as an Admin. No results 
If anyone can help me, please do it… It’s really annoying, to get over this whole process.
I found this. And it worked for me.
