PS5 PRO performance issues: Constant stuttering.

​

I bought a PS5 Pro one month ago, and it worked completely fine for the first three weeks. However, it has recently started stuttering. This happens every 2 to 10 minutes, depending on the game.Interestingly, I haven't noticed any stuttering in lighter games like Astro Bot. But in more demanding, heavier titles like Resident Evil 4 Remake and Spider-Man 2, the stuttering occurs quite frequently.I have already tried clearing the cache and rebuilding the database, but it didn't help. I also have plenty of storage left (over 600 GB of free space on my SSD).Has anyone else encountered this specific issue? If so, how did you fix it? I would appreciate any help!
