Hello @Anonymous ,
Welcome to Microsoft Q&A forum.
It seems that the conflicts still exist. Here are some similar threads(for VS, for VS Code, or for other extensions) which discussed about this issue/similar issue => Tab completion conflicts [GitHub Copilot], Copilot with VS 2022 is often very disruptive by cancelling out regular intellisense, Regular IDE autocomplete and Github CoPilot must work together.
You may consider disabling IntelliSense to make the Tab "select" Copilot suggestions. I recommend submitting a ticket on Github Community for further help.
Sincerely,
Tianyu
