MAC M3 Air 16Gb 512

This is my second Mac that I purchased within 2 weeks and both were extremely slow. Apps don't open, and I have to force quit them and keep on sending the "report" to Apple, but how many times would I need to send back the report? The messaging and App Store apps don't open and keep signing me back in for my messages even when I sign out and then close. Being that it's my second Mac with the same issue, I wanted to come here and see if it's the model issue and if I should try another model while I'm still under warranty. Anyone else having same issues? It's a brand new laptop so there is no ram issues and I have 16gb with 512 so not sure why same model second computer performing so slow or not at all?
