This is to confirm that kubuntu-21.04-beta-desktop-amd64.iso fails as an installation media on my PC. I have nvidia graphics, amd m/board and am using 'safe graphics' when attempting to boot up the installation media from a thumb drive. The usual "Installation failed" message is displayed. If more info would help please give me any further instructions.

Cases where the crash can be triggered: - Using a Virtualbox VM, where graphics acceleration is handled by mesa with LLVMPIPE - Start the ISO on real hardware in 'safe graphics mode' Cases where the crash is not encountered: - Start the ISO on real intel (HD graphics) hardware with full acceleration. NOTE: The crash can be avoided by downgrading MESA 21.0.x packages to the previous 20.3.4 in hirsute. Try/Install crash: Screen fails to start, or starts then crashes on any user action. The user is presented with: "Installation failed - The installer encountered an unrecoverable error. A desktop session will now be run so that you may investigate the problem or try installing again" Live session crash: The installer does not start from the desktop icon. Starting ubiquity from the terminal results in an "Aborted (core dumped)" message and nothing else.
