Thank you for the bug report!

However Plasma 5.24.7 is no longer eligible for support or maintenance from KDE; supported versions are 5.27, and 5.27 or newer. Please upgrade to a supported version as soon as your distribution makes it available to you. Plasma is a fast-moving project, and bugs in one version are often fixed in the next one.

If you need support for Plasma 5.24.7, please contact your distribution, who bears the responsibility of providing support for older releases that are no longer supported by KDE.

If you can reproduce the issue after upgrading to a supported version, feel free to re-open this bug report.

This does not happen for me on plasma 6.
Running kscreen-doctor iopiop or with other non-command text does not hang, and returns 0.
In this case i think it should return 1 and inform the user in some way (maybe prompt to use kscreen-doctor --help).
