Sorry to hear about your difficulties. A few questions to better understand the issue.
- Would it be possible to share a screenshot of the error? - Does this happen with all projects or just this one?
- Is the error preventing you from being able to use the app altogether? - I wondered if the error might be related to available RAM rather than free storage space. Does restarting the device or closing any other open apps make any difference? - What type of device are you using?
Please get back to us with more info and we'll try to help.
