Videos shot with the Sony Alpha 7S III (ILCE-7SM3) are killing the Primiere

Creating different proxies didn't help, and moving the data to another SSD didn't help either. The interface is very slow, and the program has a lot of trouble recognizing files from the Sony Alpha 7S III camera. Resetting the settings and clearing the cache didn't help. Who should I contact? Which developers should I reach out to? The problem is specifically with this one camera! It feels like I'm working on some really old hardware from the 2000s. In other programs, these files run very quickly without using proxy files.
