My map tab is lost

Hi, last season I had my map tab, I couldn't continue playing but now, a few months later I come in and I no longer have my map tab, I realized after pressing the transform maps button on the old map tab (the one from last season, read-only), is there any way to get my map stash back? I had just bought early access to poe2

It will be unnamed near the end of your tabs, but will have the Map stash logo. Look carefully for it.
