@uLawPractice SuperfluidSoftware Inc , By tracking the correlation ID, I found that the reply url mentioned in the request is ending with OneDrive/ but the reply url configured on the application (with client ID in above error) is ending with OneDrive (without a slash at the end).
Kindly update reply url in the application by navigating to Azure Portal > Azure Active Directory > App Registrations > All apps > Search with client ID (aka app ID) > Under Authentication blade of the application > update the reply url with a slash at the end.
