Mac apps stop responding despite restarting

I only just recently updated to Catalina, the first two days were fine, I shutdown my computer and when I rebooted, the reboot took quite a while, after rebooting, I tried to open certain apps but they were not responding, even Settings, it would not let me logout, restart, or shutdown, so after force powering down my Mac and restarting twice, it is in general slow, and after finally opening an application (only certain apps work), it runs for a small amount of time before it stops responding for a while, before becoming functional again, repeating this cycle, any fixes? Thanks
