The iniBuilds A380 is a Microsoft Flight Simulator add-on, and MSFS isn't available on PlayStation 5, so I'm a bit confused — are you actually running this on PC or Xbox? If it's a PC/Xbox install, a freeze on "Start Flight" is often worth chasing by confirming the add-on is fully updated and that no conflicting liveries or similar mods are loaded. If you really are on PS5, then it may be a different product entirely, so it's worth clarifying before anyone digs further.
