Yeah, my understanding is that SARS-CoV-2 has a proofreader enzyme that error corrects, which ensures fidelity during replication. In other words, it mutates a lot slower than say the flu.

The polymerase it uses to duplicate contains a profreading function. Its a big virus too:

A way detailed presentation on the Virus: (I think about 40 minutes in it talks about the duplication). Its kind of an interesting talk:

It might be the case that the current virus is already very good at its job, new mutations are now able to compete.
