Image Transformation Issue

My project was working with images normally, I never processed them or anything, and today, suddenly when trying to add or update images from the project, it started returning the error:

code: 403, type: 'storage_image_transformations_blocked', response: { message: 'Image transformations are blocked on your current plan. Please upgrade to a higher plan. ', code: 403, type: 'storage_image_transformations_blocked', version: '1.6.2' }

Why? Can't I use images on the free plan anymore? Because I didn't do any transformations.

Transformations are supported on paid plans, please see -
