Description
The Webengine fails to start, and an error is logged about Chromium (Windows and Linux) :
[15624:15300:0525/094905.378:ERROR:sandbox_win.cc(1052)] Failed to launch process. Error: 32
[15624:15300:0525/094906.977:ERROR:sandbox_win.cc(1052)] Failed to launch process. Error: 57
This is exactly the reference example here and here.
EDIT: on Debian, it causes crash of entire machine (total freeze, then you need to reboot), with or without QTWEBENGINE_DISABLE_SANDBOX.
