F1 24 (f1 world) multiplayer: Players keep disconecting

Guys I need help. I recently got F1 24 on my Windows 11 PC. I have a friend with the same setting. We want to play together, however its not working ever. I've tried LAN-games (he is in the same network), result always error when joining. When hosting a F1 World multiplayer grand prix, after approximately 10 min the symbol for player disconnection comes up and he is moved in a separate lobby. I've cleared the cache and repaired the game via the EA-App. The following report code is provided in the game: ABEE-KVJP-DJHH-SSJD. Whatever I've tried, after max 10 min the multiplayer experience (usually mid qualifying) is over. It's becoming increasingly frustrating and not worth playing anymore. If anyone has a similar problem, please help. My (and my buddies) internet connection is very good and stable and has never (in any game) been a problem before. Always shortly before my buddy is kicked out, the yellow symbol is on the left and his car is teleported in the garage. 

Best
