I've tried that using the user guide here:
https://www.semantic-mediawiki.org/wiki/Help:Installation/Quick_guide
by adding this line to composer.json
"mediawiki/semantic-media-wiki": "~3.0"
then with i changed it to: "~3.1"
then wiki pages are working fine, but when i tried to do some changes in template, module, category, then this error comes.

by the the way, i did all the steps, including the maintenance script of semantic mediawiki, because it's not a fresh installation.

how to get version 3.2 using composer, when i tried to change to "mediawiki/semantic-media-wiki": "~3.2", it didn't works,
Problem 1 - The requested package mediawiki/semantic-media-wiki ~3.2 is satisfiable by mediawiki/semantic-media-wiki[3.2.x-dev] but these conflict with your requirements or minimum-stability.

thank you

SMW 3.1 is not compatible with MediaWiki 1.35 and MW 1.35 is not yet released. SMW 3.2 also has not been released.
