Thanks for your help but nothing change.
This is what i try:
-Upgrade to last 7.2.6
-Delete user profile
-Try on other user session
-Update graphical driver
-Reboot

Does LibreOffice have logs file anywhere to see where it stop his launch ?

Of course, something could have already gone wrong during the installation:

For the computers on which LibreOffice is not launching, start in safe mode. Click start menu - LibreOffice 7.2 - LibreOffice (safe mode) - Continue in safe mode.

Then click Tools - Options - LibreOffice - View and untick the box Use Skia for all rendering and click OK. Restart in normal mode and hopefully, LO will start OK

Unfortunately i have same problem after that.
But it’s weird because i uncheck Skia, restart LO in normal mode and not work.
I restart in safe mode : Skia is again checked.

I found a workaround by modify

%APPDATA%\LibreOffice\4\user\registrymodifications.xcu

<item oor:path="/org.openoffice.Office.Common/VCL"><prop oor:name="ForceSkiaRaster" oor:op="fuse"><value>false</value></prop></item>
<item oor:path="/org.openoffice.Office.Common/VCL"><prop oor:name="UseSkia" oor:op="fuse"><value>false</value></prop></item>

But how i can force this anywhere ?

This is from First steps to take before submitting a bug - The Document Foundation Wiki ?

From User Profile: on a normal Windows install, %APPDATA% resolves to C:\Users\<user name>\AppData\Roaming, at least on English versions of Windows Vista and later

Thanks, next time i have the problem i will do this

If the issue is gone, locate <user profile>/cache/skia.log, and attach it to the bug report. This will help the development team assess whether the issue could be with the Skia/Vulkan implementation in your system, or within LibreOffice.
