If you take a call or otherwise disrupt the AR session, it is recommended that to restart the capture process for that room. All previous rooms will be unaffected. However, the model is likely to be skewed if it can't capture the entire room at once.
While restarting the capture process from the beginning may seem inconvenient, this is a better option than submitting the project and having it listed under review and then having to re-do it anyway, which will take more time.
