opera gx taking 21 gb of ram ?????

i was learning blender and was doing a basic donut and mug but my pc was overheating a bit, i just got my pc so it was kinda weird that it struggled with blender (with the little things i had) or so i though. After closing blender i still had the issue of like 50% of my cpu being used and my pc heating a bit so i checked task manager and saw 21 gb of ram being used. Mind you i had 10 tabs thhem being 1 chatgbt, 1 op gg and the rest youtube so not really that much. To stop it i used the ram limiter which at first didnt work and afterwards crashed opera to come back to normal. Is something fishy happening ? (couldnt get a screenshot sadly)
