Search doesn’t work

Hello. The search button does not work, it does not do anything directly, neither by pressing the button nor by pressing enter.

I don’t know if it’s because of the update to WordPress 6.0 or what.

It’s on my website below everything in the right panel, the one above is a plugin that I put to get out of trouble and it only works in Ajax, normal doesn’t work either.

Thank you!
