Can you see from above where it's coming from? Clean it all up and then look again after a ride maybe. When I had a leak I couldn't find the cause myself so took it to the bike shop to sort. Turned out to be valve cover gasket and also (main leak) was from an o ring deep inside.. I think it was oil pressure sensor area.

Oil pressure sensor was the culprit here:

I had that exact leak but not as bad. Had too do with a gasket. I did my best too find it by cleaning up etc.. but couldn't locate it. Brought it too the shop and it took them two times too fix it. but finally it was sorted out. Around $300 if i remember correctly. Good luck

The oil leak is coming from the bolt with an allen head ( on top of the first photo). , the allon bolt in particular seen in the second photo.
Would this be where the oil sensor is located?

It more likely that that's just where the oil is settling rather than where the leak actually is. Have a look from above and see if you can see the leak higher up.
