Hello,
Also which processor do you have?
You could try updating your NVME SSD firmware, it can help in some cases. If you have a Western Digital, you could try this: Western Digital Drive Update Guide Without Windows/WD Dashboard - #66 by BrewCoffeeAddict
You could also try sleep with or without bluetooth or any connected devices to see if it makes a difference.
You could also try to ask on the Zorin forum: https://forum.zorin.com/
