The pull-down selection is not possible in Bootloader

Hello,

I have installed OpenMV IDE 4.0.1.
I tried to update the board’s firmware to the latest, but
The pull-down selection is not possible in Bootloader window,
Could not update.

Because I turned off the update check at runtime in OpenMV IDE,
The update confirmation screen does not appear.

Please tell me how to update new firmware or downgrade OpenMV IDE.

Thank you.

I found an older version on GitHub.
I was self resolved.
Thank you.

Could you clarify on that? The new IDE should be able to resolve all bootloader issues much more reliably than the previous IDE.
