How to reverse and transpose a row?

I try using the formula in this post.

https://stackoverflow.com/questions/70404655/google-sheet-how-to-reverse-and-transpose-a-row

The formula works well when the range is directly referred in the formula, see below:

However, when let function is used and a function is used to create a range. It returns error, see below: (This is a replica of my worksheet and there is a reason that I created a range using another function.)

I have some checking and find that the error was caused by TRANSPOSE(COLUMN(Range1)), would you please advise any idea of this case?

The sample sheet link is here:https://docs.google.com/spreadsheets/d/1KsxpdBz2n3Dmw_HV3vHBcJ2XP8H1-5UdlJpeyACo2MA/edit?usp=sharing

Thanks.
