Igor, is it possible to download KDevelop 6.1 for Windows 10, 64-bit somewhere?
Or what is the last version for Windows? I have KDevelop 5.5.0
5.5.0 is probably the last one on Windows. Merging https://invent.kde.org/kdevelop/kdevelop/-/merge_requests/694 can produce continuous Windows builds, though no one has tested them yet, so they will not necessarily be functional.
