It seems you are hitting typechecking ice. Would you open script analysis widget to see what’s the error/warning message on it? Also would you check what beta features you are enabling?
Reporting bugs is fine and should always be reported if they are creating barriers while exploring or interacting with Roblox products and features, from websites to software (ie Roblox Studio).
However, when it comes to having a problem and you discover that it is because of one of the beta features, that is not a solution. This is the root of the problem you are facing. And with this being pointed out, Roblox engineer(s) will utilize this piece to fix internally and deploy a solution.
Until then, without their responses, you shouldn’t mark your replies as what @bvetterdays said. Only mark as a solution when they provide updates on this thread and state that everything is working normally.
