Game lagging horribly after 1.17.34 update on mobile

After getting the 1.17.34 update on my Samsung A51, all my worlds have been lagging slightly, until it begins to rain in the current world I am playing, and then it starts lagging horribly and I mean frame by frame crawling and struggling to keep up. I've tried giving my phone a break, restarting the Minecraft app, and even restarting my phone, but it just keeps lagging and before the 1.17.34 update, Minecraft ran super smoothly on my phone so I know it's not that my phone can't handle all the generations that happen. Please fix it, because my phone is the only way I can play this game. Thank you.
