Do you want to change the language for OneDrive client?
If yes, please go to Start meun > Settings > Time & Language > Language, check the display language for your Windows system.
The OneDrive client's language depends on the system language.
If the display language and the preferred language is English now on your system, but the OneDrive client's languag is still French, I suggest you uninstall OneDrive and restart your PC.
Then download OneDrive, and reinstall it to check this issue.
