I just redownloaded from Gitea and I still cannot reproduce:
Maybe you can try redownloading, maybe something went wrong during the download.
I wouldn’t download each file one by one, what I did was downloading the entire branch first:
The zip file is only 75.27 MB, not very large.
After downloading, in the unzipping program, we can select the colormanagement folder, and only unzip that folder.
That’s what I do every time. No need to download each file individually.
