Concert settings

Hey, hope this is okay to post on here. I have my first photo pass gig tomorrow with my new Canon EOS R50 with the kit lens (RF-S 18-45 mm Zoom lens).

I’m trying to practice with it in low light and I’m struggling to get any clear photos and the auto focus is stopping me from taking most of the pictures I try to take.

Any advice on the settings would be greatly appreciated.

As I’m really anxious that I’m going to leave tomorrow’s gig without any pictures.

I know I need a better lens but that’s not an option (for tomorrow’s gig)
