I can’t write a new post

Hello,

First, sorry for my English… I will try my best to explain my issue.

I updated to the last version of Yoast SEO (9.0.2) then I started a new post. And, while I was writing, the post refreshed to a broken page. I tried again, it was impossible to stay on my post for more than a few seconds before being redirected to a broken page from Chrome. Everything is fine on the rest of my blog, I have not found other issues so far. So I first deactivated IP Geo Block as I had issues with it in the past but the issue was still there so instead I deactivated Yoast SEO and the issue is now gone.

Here are a list of all my plugins, just in case any of them conflict with Yoast: Ad Inserter, Autoptimize, Contact Form 7, Contact Form 7 Image Captcha, Cookie Notice, IP Geo Block, iQ Block Country, Loco Translate, PE Recent Posts, Re-Add Text Justify Button, Related Posts, Smart Recent Posts Widget, Widget Areas, WP 404 Auto Redirect to Similar Post, WP Font Awesome Share Icons, Yoast SEO.

Thank you for your help and attention.
Best regards
