Repeated Crash

So like the title said, I experienced repeated crashes, like 3 times in 2 hours. The thing is that I play games like Wuthering Waves and Mobile Legends for hours, but doesn't experience any crashes.

​

I know the issue is because of my phone, but I'm also kinda curious because I made a new account (currently at TH 4) where I found out that you can unlock the Barbarian king as early as TH 4, and I'm currently at TH 4, but my main account is TH 16. And that's the issue, I've never experienced any sort of crash before I made this new account, and it only happens when I attack, or when I deploy the CC troops, this only happens to my TH 4 account, my TH 16 and other accounts doesn't crash, I don't know why though.

​

Well that's all, I just wanna share. Btw my device is Poco X7 Pro.
