Apps not working on S23ultra

I am new to this KWGT pro. After i did the purchase the playstore says this app was made for the older version.
What can i do now ?

Do you mean the app itself or one of the packs suggested in the app? For the packs I can’t do much as those are created by third parties and have not been updated, unfortunately Google started to block apps made for old API even if they are working well. You can still find those packs outside of the Play Store.

You can find some here or on Reddit.
