HELP! Unhandled internal error

URL of experiment: Haven’t been able to launch it online

Description of the problem: When I try to launch the experiment online from the builder, this message comes out:
Traceback (most recent call last):

wx._core.wxAssertionError: C++ assertion “!(flags & wxALIGN_RIGHT)” failed at …\src\common\sizer.cpp(2098) in wxBoxSizer::DoInsert(): Horizontal alignment flags are ignored in horizontal sizers

I have seen similar posts, but there are no answers or solutions to them. Please, help me. I really need to make this experiment work. I posted a similar message before, but I didn’t get any reply.
HELP ME, PLEASE!

Hey prisma! Could you repost this issue in the builder category? Then we’re sure the right specialists will pick it up.

Thank you! I already posted it. I got a reply and I’m just waiting. Hope they can help me. Thank you anyway.
