After update WordPress, Website shows the white screen of death

Recently, I was Launch a WordPress tutorial Blog, but today, when I update WordPress’s new version, The Website shows the white screen of death. I already contact my web host but I would like to fix these issues as soon as possible.

Any suggestion?
WordPress Version 5.3.2
My website:

Thanks in advance

It looks like you’ve found the problem, but in case there is another—I have had this issue when my permissions on my web host are wrong. It may be specific to my web host, but when I Rsync my files over, they often are assigned wrong permissions.

It’s a bit frustrating, and there’s probably a fix out there that would mitigate that problem, but I just repair permissions after the fact.

Did you set your .env file to development yet? If it is set to production your site won’t show errors.
