Try restarting windows into safe mode. Details here if you don’t know how to do it: https://support.microsoft.com/en-us/windows/start-your-pc-in-safe-mode-in-windows-10-92c27cff-db89-8644-1ce4-b3e5e56fe234
once restarted in safe mode, all drivers and other non essential windows processes will be disabled including any security/anti-viruses e.t.c. They can be opened manually by simply opening the application.
whilst in safe mode, load up battlefield, and see if the issues still persists with punk buster. You will also need to load up your graphics card drivers to avoid any potential graphics related crashes. This will allow you to see if it is a process in the background causing the issue to occur, and you can troubleshoot it from there onwards and find what is causing the issue by slowly reopening other applications and processes that would otherwise be running in the background.
