Confirmed. Reverting the commit isn't enough because there are also changes in p-d that need to be done ("fallbackConfigKey" in org.kde.plasma.desktop/main.qml).
(In reply to Luca Beltrame from comment #4) > in p-d that need to be done ("fallbackConfigKey" in > org.kde.plasma.desktop/main.qml). Rather, reverting the commit makes the fallbackConfigKey in p-d not readable anymore (at least when I tried).
Scratch that, I probably did something wrong in my checkout.
Git commit 1d68bc118a1b0eb0e3ce1bc25c17c781cd6cead5 by Luca Beltrame. Committed on 24/04/2021 at 22:15. Pushed by lbeltrame into branch 'master'. Revert "Save layouts per-resolution" This reverts commit 1390b55188e032336a9e92fb74bd55260493f1eb. At least this prevents plasmashell from crashing until a solution is found.

Git commit 66f620995bdfdc21d1a22e5ec18170ed5ff4d2ed by Marco Martin. Committed on 27/04/2021 at 11:20. Pushed by mart into branch 'master'. Don't assume m_containment is there The containment property is assigned from qml so it can be bull. Also, if this component is used in a plasmoid that can run also in normal applet mode (i.e. folderview) it will be null in that case. if we don't have a containment assigned yet, just do nothing in the signal handlers as they are supposed to read and write from the containment config M +68 -32 components/containmentlayoutmanager/appletslayout.cpp M +22 -2 components/containmentlayoutmanager/appletslayout.h https://invent.kde.org/plasma/plasma-workspace/commit/66f620995bdfdc21d1a22e5ec18170ed5ff4d2ed
