Having problem to create a New Post

Hello All,

I created this site around 4 years ago, everything was working 2 months ago but now I have a problem creating new posts in my WordPress dashboard.

When I try to create a new post, It’s loading for some time & showing a blank screen after that. I have uninstalled all plugins and tried to create a new post but still have the same issue. After that, I activated Twenty Twenty-One default wp theme and try to create a new post but there was no success for me, it’s still showing a blank white screen when I create a new post.

Let me know if anyone has the solution to this problem.

Thanks in advance
