all spaces disappeared twice when using external monitor

the first time, i had my macbookpro open and connected to an external monitor i created 15 different spaces, when i closed the macbookpro, all the spaces disappeared.

With the MBP closed, i created again all the spaces. When I had to open the MBP, all of them disappeared again.

Is there a way to take a backup of the spaces and restore incase it is lost.

each time i open or close the MBP, the number of desktops changes, is that what is causing the issue
