Unable to open material windows, UI widgets, and other separate windows from UEFN after the latest patch.

Hello everyone, maybe someone else has encountered this, but after the last patch, I can’t open my material files, UI widgets, and similar separate windows in UEFN. Only the main UEFN window works, while when I try to open a new window, for example, for a UI widget, it either loads endlessly or doesn’t load at all.
