Need advice about career switch

I'm stuck in a role that doesn't have much of a future ( IAM security) but I want to get into devops/cloud engineering I'm already at 2.5 year in the current field trying to upskill, work hours are hectic , upskilling after work is also hectic unless I wake up at 5 am it's not going to workout.

I feel really burnt out sometimes, how would you guys approach this.
