left crank falling off

Tried to go for a mtb ride today, left crankarm (Surly Mr Whirly) came loose. With my multitool I was able to wrangle the two pinchbolts and get it back on, 5min later it was falling off again. So I put it back on a 2nd time and rolled downhill back home (without making it to the top )

Is the whole crankset toast, or could I get by with a replacement left arm? Where could I even find one? A little searching did not turn up any left arms (hardly any whole cranksets, and those were ungodly expensive! (for me)) Does Surly even sell cranksets anymore? Their redesigned website doesn't have pages for any cranksets, and only shows two chainrings, there used to be so much more

Are there cranksets from other brands that would mate with the mr whirly splines? I wouldn't mind a frankencrank.

Or can anybody point me to cheap 1x cranksets with 58bcd? My surly 28T narrow-wide chainring is nearly new, and I'd hate to have to ditch it.
