The website has technical problems

Hello! all sites stopped working for me, instead of the site the inscription “The site has encountered a critical error. Please check the administrator’s inbox for further instructions.

Learn more about troubleshooting WordPress.”

I can’t log into the admin panel either, there is also an inscription about the problem. A letter comes to the mail where it says that the Redis Object Cache (version 2.1.4) is to blame for the problem

WordPress version 6.0.1
Current Topic: Cook It (version 2.1.6)
Problem plugin: Redis Object Cache (version 2.1.4)
PHP Version 8.1.6
