Error 404 when performing a search

Hello everything is fine?
I have a problem with a site that is as follows:
Whenever I try to do a search, it gives the following error:
https://prnt.sc/brrQrocg-IHD
https://prnt.sc/cP8Fp1s5i981
I don’t know what it could be anymore, I cloned the project, I removed all the plugins, I left only Elementor and Elementor Pro, but it only gives me this error, what could this 404 error be?
I already left only the free version, I can’t imagine what it could be, in the local host, it only has it and it doesn’t work, I would like to know what I can look for to solve this issue.
