I have a problem that after installing bigsure 11.5.1, it can't shut down and sleep, it becomes a reboot. Everything else is fine. Please tell me how to check the problem?

This sounds like a USB mapping problem. Have you used my SSDT files or created your own with ssdttime? Also the USB mapping kext is important. You can check in IORegistryExplorer what ports are active.
