After a full evening of debugging, the root cause turned out to be Windows’ default path length limitation. Even with a repository path like C:/Users/Micha/Development/PowerToys (which is not unusually long by itself), the combination of folder structure and file names exceeded the maximum allowed path length and caused the build problems. --------- Co-authored-by: Niels Laute <niels.laute@live.nl>
