Short description of error
After creating a texture in the texture slot and hitting undo to delete it, if you hit redo it will re-add the texture previously removed, but the interface in the texture slots will not update to show this, and the render will still be pink in solid mode and lookdev mode.
"Workaround": after redo, paint a stroke to update the texture, and then switch the rendering mode to update it and show the change. It will also update the UI in the texture slot appearing the texture back again.
Exact steps for others to reproduce the error
1 - File > New > General
2 - Select "Texture Paint" tab
3 - In "Texture Slot", add a new Base Color, default settings and OK
4 - Hit Undo
5 - Hit Redo
