How to recover from invalid/old DEXT tokens

When I tried to swap my Eth to Dext tokens, Metamask selected the invalid or old DEXT tokens that are worthless. Thus I have lost funds worth of $9K. Is there anyway to recover these tokens? Like swapping the old tokens with the new ones like some exchanges did un July? I’m chocked to find out that Metamask allows swapping the old/invalid DEXT tokens that was taken out of the market more than a month ago.
