Problem with settings saving RESOLVED

Hello everyone
I've got a problem with settings saving. After changing some settings in fusion9 (hotkeys, preferences...) , and tape SAVE, nothing was applied after restarting Fusion9.
But in AppData/roaming/blackmagic Design/Fusion/profiles/default, everything is correctly saved
Any suggestions ?

P.S. Thanks to Blackmagic, for this absolute amazing softwares (fusion9 and resolve14)

Windows10 familial
Fusion 9.0.1 build 3
Intel I5 - 16go RAM

OK resolved. Do not use accent in windows10 account name.
Fusion don't like.
Create a new account and all OK
Au revoir...
