Libre Office ghost instance

[ghost]

At certain times, when opening Libre Office documents, when we try to access the window, material shell redirects us to the first window of the virtual desktop, with this error :

gnome-shell[27183]: Object .MsWindow (0x564fe4ced920), has been already disposed — impossible to access it. This might be caused by the object having been destroyed from C code using something such as destroy(), dispose(), or remove() vfuncs.
gnome-shell[27183]: Object .MsWindow (0x564fe4ced920), has been already disposed — impossible to access it. This might be caused by the object having been destroyed from C code using something such as destroy(), dispose(), or remove() vfuncs.

It can be accessed by double-clicking on the libre office instance. If you move the instance to another virtual desktop, two windows are available: a window containing the libre office file and another ghost instance. When you close the Libre Office window containing the file, the ghost window remains and this error appears :

gnome-shell[27183]: JS ERROR: Error: Assertion failed: Expected the MsWindow to be in the 'window' state
                    assert@/home/hemlee/.local/share/gnome-shell/extensions/material-shell@papyelgringo/extension.js:251:15

                    onNewMetaWindow/<@/home/hemlee/.local/share/gnome-shell/extensions/material-shell@papyelgringo/extension.js:9197:18

And if you try to move the shadow instance to another virtual desktop, gnome crashes.
