US Immigration from Midway Islands

So I applied for naturalization after I divorced my ex wife in 2020 I became a US resident back in 2014 through marriage I been only married once.. I came to naturalization interview on april 6 2022 when I got there agent told me that I have mail an I407 form giving up my LPR wich I didn't of course.

My ex wife did she filled it up in ink and she had an google document picture of my signature that she use (note that signature wasn't filled in Ink).... Now im stuck until I can get any evidence of she doing this Uscis agent pass my interview but couldn't make a decision yet.. My lawyer said not to worry about it but im really freaking out.. Did I loose my residency?? How can it be? I just paid taxes I opened a business back in 2020 too

Any advice? thanks!
