Extended video recording with iPhone 15 Pro w/256GB

I need to record a 90-minute choral concert for cut-away shots in a semi-pro video. The setup will be a stationary shot of the conductor. Video cameras will be used for the chorus and soloists. It will all be combined in post-production. I have read the iPhone 15 Pro has had difficulty with freezing during recording. Is there a fix or should we look for other recording options? Best quality would be the first choice.
