I can't help you with running shoes but I'm sure that trying different shoes are worth a shot.
For cycling, it's fairly common but you are getting it very fast.

You should consider wider cycling shoes, moving the cleats further back on the shoes, maybe different pedals if that doesn't help... insoles or arch supports and maybe don't tighten the shoes more than you have to.

Can't help you with the running part either. But I did get numbness in my toes riding. In my situation it was a combo of getting better fitting shoes that handled my wide/flat feet, a little bit of cleat position (but not much, more for my knees) and the right saddle. Once I got all those figured out no more numbness. Running ISM/Adamo saddles currently and it's what works for me.

But, I find it harder to ride long periods on my fluid trainer because it is fixed in place. Rollers I can handle a bit longer but I don't stand up on those to get those minor "breaks" on the sit bones like real outdoor riding forces you to (stops, intersections, standing efforts etc).

Wider and/or bigger volume shoes both running and cycling.
Maybe play with the laces on your running shoes skipping a lacing hole if you feel tightness/pressure over a particular spot.

If you post what running shoes you're currently in I may be able to give you shoes that have wider toe boxes. Going to a 2E is another possibility
