Everything broke in the unreal editor

Hi all. Material editor windows, blueprint editor windows, mesh editor windows open empty. The content browser opens empty. The camera in the viewport does not move to the left and right when the right mouse button is pressed. If you correct the Saved\Config\Windows\EditorPerProjectUserSettings.ini file, specifying the following there:

[ContentBrowser]

ContentBrowserTab1.VerticalSplitter.SlotSize0 = 0.250000 ContentBrowserTab1.VerticalSplitter.SlotSize1 = 0.750000 ContentBrowserTab1.FavoriteSplitter.SlotSize0 = 0.200000 ContentBrowserTab1.FavoriteSplitter.SlotSize1 = 0.800000 ContentBrowserTab1.FavoriteSplitter.SlotSize2 = 0.400000 ContentBrowserTab1.ViewMode = 0 ContentBrowserTab1.ThumbnailSizeScale = 0.180000 ContentBrowserTab1.CurrentViewType = 0 AssetPropertyPicker.ThumbnailSizeScale = 0.100000 AssetPropertyPicker.CurrentViewType = 0 AssetDialog.ThumbnailSizeScale = 0.100000 AssetDialog.CurrentViewType = 1

[/Script/UnrealEd.LevelEditorViewportSettings]

MouseSensitivty = .1f

the content browser starts to open correctly, the camera in the viewport starts moving, but the material editor windows, blueprint editor windows, mesh editor windows open empty. It’s not class defaults → Open Full Blueprint Editor. After a few openings/closings of the editor, everything breaks down again. Tried completely uninstalling UE4 and reinstalling it did not help. I upgraded to UE4.27 due to this issue, didn’t help. Used version 4.23.1. Any ideas on what might have happened? Where are the editors settings?

Hi fredwriter, I think someone else asked about this same problem: BP asset editor blank - Blueprint - Unreal Engine Forums

ЕраNo, thanks, but no, this is a different problem, I wrote about this in the first post.
Window menu
This window opens when I click “Open Full Blueprint Editor” in the “Class Defaults” window

This issue occurs with newer Сpp and BluePrint projects as well.
