nVidia Offload Rendering broke the Launcher

After the latest update of the launcher, the nVidia PRIME offloading rendering seems to be broken on Ubuntu 20.04. When I start the Launcher with the offloading rendering enabled the Launcher screen turn into black. After some tests with other application, the problem seems to be in the Launcher and not in the nVidia driver. Before the latest update of the Launcher everything work perfectly. When I try to run the Launcher with Intel graphics or with nVidia Performance Mode everything works.
