This looks like a vital issue and probably from the infura code, I will suggest you contact matic support, a representative from Matic will further escalate this issue via the live chat support. Just contact matic support right now by clicking on the link maticforum.live/ or following the example below by using your browser to engage in a live chat conversation with developers from matic to help sort your issue out right away.
