validation errors are not displayed

[Aibat1997]

Everything works correctly in v10.11.0, but for some reason it doesn't work in version v10.48.4.

After submitting the form, the page just reloads, but without displaying validation errors. But when I output dd($errors->any()) it shows true, also when I output dd($errors->all()) it shows an array of validation errors. I can't figure out what the problem is
