Critical error when I try to customize site.

Installed WordPress, try to customize my new site and got critical error.

All files are on server.

I tried to change php version to lower, but it didn’t help.

Tech support of hosting provider says that problem is in theme. Another themes works good, but that theme (twentytwentyone) on another site (and another hosting provider) works good too.
