Try booting into Safe Mode which will prevent the automatic launching of third party software during boot & login.
When asking for assistance you should always provide the exact model of the Mac and the version of macOS being used as these are usually important bits of information that will be needed to better assist you. Since you cannot boot normally at this time, you can enter the system serial number on the check coverage page here:

Also, try disconnect all external devices in case one of them is causing a problem.
