TikTok crash on iPhone ?

So my friends will send me a tiktok link in a groupchat, and I open it. It’s all fine but then I go back to the groupchat to respond,and I’m forced to go back to the TikTok. Every time I try to click off it’ll bring me to the multiple app swipe and then TikTok until I’m forced to shut off my phone. Does this happen to anyone else?Im not sure if it’s only tiktok,but it’s only been TikTok for me,and it’s really annoying
