AU31&AW33 , AU28&AW30 are VCC pin. VCC pins short to ground is one of the symptoms of EOS.
In order to avoid electrical damage, the device should always be handled in a static-free environment and all the input signals should remain within specified limits, as recommended in the PSG Data Book and associated application notes, at all times.

For your information, EOS is fall under mishandling issue.

    Hello,

    Flex has strict ESD control throughout the manufacturing process, and the personnel operation also meets the ESD requirements, so we don't think the short circuit is caused by EOS. We hope you can arrange the failure analysis and find the root cause.
