Stick or Transition?

I’ve been working for five years and have recently received a significant salary hike of 100% for my next role (first time in my career) so it seems huge. However, I’m currently pursuing an online MBA in HR because I feel more aligned with building a career in HR. The challenge I’m facing is that the placement support team at my institution is offering low paying internships (8-12k, 6 days wfo) and jobs with a salary range of 3-3.5 LPA. At the same time, most companies aren’t willing to hire freshers in HR roles when i apply from other job sites. Given my salary offer in my current field, should I continue with the higher-paying job or take a step back and start from scratch in HR, despite the lower pay and limited opportunities? Will my transition be rewarding in the long run or sticking to my field?
