macbook air keyboard and trackpad stop working after waking from sleep

I'm using the latest version of macOS Catalina on my 13in 2019 macbook air, and almost every time I wake it from sleep the keyboard and trackpad disconnect for up-to 4 minutes, and if I leave the mac open it doesn't do this. this is really annoying because i need to wait an extra 4 minutes at the beginning of class to start using my mac even when its on and unlocked
