Permalinks not working

First my permalink was like this https://kavandeo.com/?p=123

now i changed to /%category%/%postname%-%post_id%.html

& i allowed acess to htaccess & it rewrited the rules

i installed permalinks migration & set old structure as /?p=%post_id%

but when i navigate my site the pages are working properly as it is redirectioning from old url as well as new url

my posts & categories & others are redirectiong from my old url to the new url but when we are going to access the new url it is showing error 404 page not found
