Independent contractor converted to W-2 from 1099 due to CA labor law change; can I claim expenses?

I was working as a software consultant at a consulting company in 2020.

I was on 1099 in January but because of the labor law change in California, my client was forced to classify me as a W-2 employee starting February. Nothing else changed; I was using my own computer to perform the contract. Can people in the situation like me still claim business expenses? Or I can't just because I

am classified as a W-2 employee at all?
