I can't upload my project with an extension

I was making a Christmas and I worked hard, on mobile, the stage width is 240, when i post, happens this:

That look weird, so I need to remove the extension, but when I remove TurboWarp's extension I downloaded, my blocks I added on my project deletes himself, and UnsandBoxed blocks will corrupt my project and my password changes with my e-mail

you need to wait two more days. the requirements are that you have uploaded three or more projects, and your profile is older then five days. after that, go to your profile and click the rank up button.
please say what extension you removed, and what blocks from it you removed, as the project should not be corrupted and removing the extension should not delete any blocks other then those from the extension.
