There is no bug, maybe you should be a little more descriptive, but if mame is crashing then thats a mame issue, but its more likely your romset and emulator version do not match.

have installed a full romset with mame and it matches the right version so might be my pc .

only started  happening since i updated launchbox and upgraded to win11

In order to help troubleshoot issues with MAME, please provide the following information:

• Do the games work when starting them directly through MAME?
  • Start mame.exe, select a game and press Enter. 
    • Does it run?
    • Or do you get error messages? 
      • If so, what game are you trying to run and what exactly is the error? [provide a screenshot if possible])
• What version is your MAME emulator?  (example “0.246”)
• Are the ROMs you are using match your version of MAME?  (example “0.246”)
• What version of LaunchBox are you using?

Screenshots

• Go to Tools, Manage, Emulators, select the emulator you’re using for MAME and provide a screenshot of the following sections
  • Details
  • Associated Platforms

• Select one of your Arcade (MAME) games and click Edit (or press Ctrl+E). Provide a screenshot of the following sections
  • Metadata
  • Launching
  • Emulation

This fix worked for me.  Hope it will help you out.

*This is done within Launchbox  Desktop, not Big Box but it will carry those setting over, Good Luck*

1) go to your manage emulators, edit your mame

2) on the left column click "Startup screen"

3) Click the box "Hide all screens not in exlusive Fullscreen mode"

4) on the startup load delay you can move it up to 5 to 7 secs. (This may not be necessary with check the box in step 3. I haven't experimented with a shorter delay time than 5 for my setup.

I've had issue as yours anytime i try run a 3D game such as Blitz.
