How do I fix my tools in my game?

All of a sudden whenever a select a tool while testing my game, I turn upside down and I can't move. Is this a script doing this or Do i need a script to prevent it? (some of the tools were basic roblox tools
that I didn't change)

This is a building help question, however there may be an issue if it's anchored which will move your person upside down.

Unanchor the "Handle".
