Can you help me with the website?

Hello friends, I'm not sure if I posted this topic in the wrong place. If I made a mistake, I apologize. My website (https://vayyy.be) has had its ad display restricted due to invalid traffic. I continue to post content daily, but my question is related to my novice mistakes with the domain. 1) I've learned that .com domain is more important, so I want to continue my activities with a .com domain. In this case, do I need to reapply for AdSense when I open a new website? 2) If I close the website mentioned above and delete its indexed pages, will it cause any issues if I use them for my new website? (All articles are my own work.) 3) Do I need to continue producing content on the existing site until the account restriction is lifted? Or should I open a new account and start from scratch? It's a bit lengthy, but due to my inexperience, I opened a site with this extension. Now I want to resolve this issue without losing my existing rights. Good evening.
