Hello @Qualkonn and sorry for not responding earlier!
This issue is pretty common and it can be fixed by deleting your local files. All your progression, credits, stats etc are still save on EA's servers, but your single player progression will be reset (that is, the campaign and the arcade battles). You keep all the skins and weapons of course!
Here are the steps for PC. If you want to read the full thread I made about this, please proceed here.
PC
- Go into arcade and unequip the star cards on the class you experience the problem with. (if there are problems with blaster attachments, please do the same). Check if this solved the issue. If not, proceed to 2.
- Close down SWBFII and go into Origin. Disable the cloud savings of this game. See the screenshots below under "spoiler"
Then, completely remove "STAR WARS Battlefront II" folder from your documents, clear Origin cache one more time and then try to launch the game.
Let me know if this worked for you!
