wwise unreal engine integration plugin missing after unpdate to 5 [closed]

Question

Hello!
I have an issue with Wwise integration to unreal projects. Since my project has been updated from 5.03 to 5.1, the plugin "Wwise Unreal engine integration"is missing so I can't create any Audiokinetic assets in the editor.

Every member of my team have this issue, except one who is still in 5.03.
All my projects with different build have this plugin missing now (4.26, 5.03,5.1)

It works perfectly on the Wwise side, soundbank are correctly generated, but the plugin "Unreal engine integration" missing keeps me from doing the integration in the editor.

I tried to uninstall/reinstall all my unreal engine installed, for wwise version too but it didn't fix this issue.
Does some one have any idea about how to fix it? Is it possible to add it manually?

Thank you!
