Fatal error right after the new update

Hello, guys! I had a fatal error right after updating the RankMath plugin to the new version, 2 hours ago.
I started the update, but it got stucked at the “Updating “Plugin Rank Math SEO (1/1)”” since then. Whenever I open a new browse tag and try to access my dashboard or my website there is a “There has been a critical error on your website” message.
Can you help me, please?

I also received this email from WordPress:
