Lost my fusion after reboot ?

Hello,

Yesterday I have made nodes in fusion but after a reboot I cannot find it today anymore.
What I get when I open the fusion tab is a MediaIn -> MediaOut with my fusion clip rendered and that's all

I am scare about losing all my work :'(

Is it a bad manipulation on my side and my work still here ?
Is it a bad manipulation on my side and I removed my work ?

I will try to explain what I have done exactly.

1 - Open DaVinci Resolve
2 - Direct go to fusion tab
3 - Start working
4- Remember your forgot to set framerate to 60 fps
5 - Copy all fusion node
6 - Create new fusion projet with 60 fps framerate configured
7 - Go to fusion tab
8 - Paste copied fusion node
9 - Continue to work
10 - Go to "editing" tab, right clic on fusion clip then render clip
11 - Save and close

Is there anything I've done wrong ?
Probably a newbie question, sorry for that :/

I answer my own question because I finally found it !
I have to right click on my fusion composition then select "decompose the clip".
Hopes it will help another guy in the futur
