I can highly recommend the CoffeeProtect plugin it's one of the best Anti-Crash/Exploit plugins on the market, in my opinion, even better than LPX. The detections are not only highly effective, but also well-balanced to avoid interfering with legitimate players. After a few updates, we no longer experienced any issues, and there were no more false positives in the console.
If you're looking for a solid alternative to LPX or a reliable Anti-Exploit plugin in general, this is definitely the one to go for. The developer, Nik, is very friendly, quickly fixes issues, and always strives to find solutions for any problems that arise.
