California: New Business, No Income, but expenses

I started business as a content creator. I started in December 2023. I have not generated income yet, but I am intending to generate income and profit. I have business expenses solely for content creation such as a computer, camera, and monitors. I have scripts prepared for upcoming videos. I released three videos in the 3 weeks of operation in December. I have reached out to a few tech companies for product endorsements to contribute to the content. Am I able to claim the business expenses?
