Hi @Can Fakioglu
I suggest you go to PowerPoint > Preferences > Select Privacy
, ensure Optional connected experiences is enabled.
Then please refer to Troubleshooting section at the bottom of the document and select 'I click the Designer button, but no suggestions are offered'. There will be some advice, you may have a check. Such as followings:
- Bad Internet Connection: Always make sure your connection is stable.
- Custom PowerPoint theme: Sometimes, if you’re using a custom template might affect the functionality of the tool. Use it on default themes.
- No content: Add at least some content like a title or a photo before asking the Designer tool to assist with suggestions.
Besides, can you use "Designer" on previous verison?
If so, it's recommended install 16.69 (23010700) to check this issue. (Please note, before re-installing Office for Mac, you need to remove existed one.)
To download this version, you may go to this article 'Release history for Office for Mac'.
