The crash is at this line https://invent.kde.org/kdevelop/kdevelop/-/blob/release/23.08/plugins/clang/clangparsejob.cpp#L184 :
    projectPaths.append(bsm->buildDirectory(project->projectItem()));
Probably the buildSystemManager is null. What project manager do you use for this project?

> Kdevelop5 crashes when opening U-Boot source tree subdirectory "net"
Do you mean opening a project with this "net" subdirectory as the root directory?
