Looking to get back into portfolio management after 2yr gap

I’ve been working for the last two years to try to make a go in the metaverse/blockchain industry and I do have a couple products that are standing up but not producing enough revenue to be sustainable as an income base for rn. I’ve had three rejections in a row for jobs that I was with well qualified or overqualified for and each one took months to complete the interview process. I’m 52 with undergrad from Boston College an Babson mba, cfa and 25 years industry experience plus the last two years of really learning the blockchain space. I’m getting scared I might not get back. Anyone offering some feedback, it’s much appreciated!
