doesn’ work properly

I bought buddypress mycred charge (paid extension)

If an user enable the profile access selling, their profile give error 404 when another user try to see it.
I tried to:
1) disable all plugins except buddypress, mycred and this plugin
2) change themplate to legacy
3) update wordpress to 5.3
4) change php version
5) update storefront theme
6) remove all additional snippets from function.php

Nothing is changed, so i think this problem depends of bp mycred charge plugin.
