Apologies for the inconvenience you have experienced. I have investigated the issue and found that it is not related to any of Joomshaper's products. Upon review, it is not possible to create any modules, not just the SP Page Builder module.
However, I have identified the cause of the issue. It appears to be server-related. Since you are using a large number of modules, the server is unable to handle the load. I recommend reaching out to your hosting provider and asking them to set the max_input_vars to 10000. This should resolve the issue.
Please feel free to reach out if you need further assistance.
Best regards
