Nothing really wrong with your workflow (except you should look at painting in a selection using quickmask) and I can get your procedure to work without error.
That error message indicates an incorrect selection, difficult to say from your partial screenshot. This example trying to resynth in from surrounding transparency. https://i.imgur.com/X6ELlau.jpg
There are selections showing, that do not come from your painted-in mask
First thing I would do is go back and check that selection.
Just for info: What version of wavelet decompose are you using? Does not quite look like the Gimp 2.10 version that I have in 2.10.8
