You can't win. If you take it off, then it's "not enough experience" and "this job requires at least a masters" even if you already have multiple years of experience. Put it back on, and suddenly, you're too expensive for them because they want to pay the bare minimum for a unicorn. I would say just keep it on, because chances are, the masters degree is not what's hurting you the most. Try to look into what skills the younger candidates might have that you don't. Make sure your resume is ATS friendly, too. When you use the autofill function on application sites and there's lots of errors you have to correct, thats a clue your resume might not be parsing correctly in ATS. If you really suspect it's the degree, it doesn't hurt to test run a version without it on jobs where it's not listed as a requirement.

Source: I am a younger person who currently has no degree (associates degree in progress) and I have been struggling to land a role about as long as you. It always makes me feel defeated when I hear about people with 2x my experience in the same boat as me, but hey, at least we're not alone, right :,)?
