Recently graduated and got a job, but now I’m doubting my career. What do I do?

I recently graduated college and I got a Software Development job. I majored in CS, but we all know how it is to look for a job after graduating and I desperately needed one so I took the first job offer I got. The thing is that I don’t really like the company and I hated the training. I got into programming because I like developing games but I don’t think I can pursue that now and I’m feeling very disappointed and sad for not following my dreams when I could. I don’t know if I should risk quitting my job to try to apply for a job in the game development industry or just stick with this job and try to find a new job on the side. There’s a lot of stress and anxiety on top of the disappointment that I feel and I don’t know what to do. What do you think I should do about it?
