Has Haachama addressed why she's not taking part in the 5th fes? I was wondering....

This has probably been answered in her streams but, ... I can't seem to find Haato/Haachama in the lineup of any of the 4 stages. I wonder if the doctor told her that she couldn't do heavy dancing or similar stuff yet. Has she ever commented on this? Thanks for answering if you have any info.
All I could find using google was someone asking it in Japanese on some site and being told that maybe it was that she was still recuperating from last year and maybe she didn't have time to prepare for it, but nothing official. Any video sauce?
