looks like it failed to find a match to resolve the next parameter
yeah, they changed the pattern again. Last time it was the next post id, now looks like it got decimal in it 
no idea, sankaku is not using standard danbooru api. You can try to use https://bionus.github.io/imgbrd-grabber/ as it more mature/maintained.
updated exe, just replace the old one [DanbooruDownloader3.exe.zip](https://github.com/Nandaka/DanbooruDownloader/files/5439465/DanbooruDownloader3.exe.zip)
because the way the server calculate the query and return the post. I think for the first 25 pages, it doesn't require `&next=` parameter if you search from 1st page,...
Should be ok if just to download the images. Tags update still broken.  Reference for the provider xml. 
try to set `verifyImage=False` in config.ini. Looks like python library cannot read the zip file format.
fyi, the latest version will skip the checking automatically if it encounter format not supported/NotImplementedError even with `verifyImage=True`
nope, as it can be updated anytime, also it has fixed filename not like image post.
you can disable the avatar download in config.ini by setting `downloadavatar = False`
