EAD misplaced by USPS : immigration

Hello,

USPS says my card has been delivered. However there’s nothing within the mailbox. USCIS says apply for substitute. However my work begins on June 1st. What are my doable choices right here?

I didn’t get the approval discover as nicely.

Can I take advantage of substitute EAD receipt as an I-9 doc?

Hoping to get an answer.
