ESP doesn't boot when it is powered via the 5V input

Likely solution, in that case: wire an 10uF capacitor between your EN and GND pins. The power supply is likely coming up slower than the duration of the reset signal as generated by the on-pcb RC network, leading to issues.

Thank you! I picked up a board recently to replace a Trinket used to control LED strip patterns with the intent of controlling them using a web interface and for the life of my I couldn't understand why I couldn't power it with the same supply I was using previously. Adding the cap solved the boot issue instantly.

I did that. The ESP boots and the AP is visible, but I can't connect to ESP's AP.

Hi George, how did you resolve this issue?
