They both landed successfully and Ingenuity was deployed. Perseverance drove away, and then failed. Could Ingenuity survive on its own?

No. Perseverance is the communications relay for Ingenuity.
Ingenuity uses essentially ZigBee to communicate, the same protocol that possibly your smart bulbs use. ZigBee has a range of about 300m line-of-sight without obstructions which is just a tiny bit too short for communicating with Earth.

14$\begingroup$ Ingenuity pushes a bit more power than a typical ZigBee and "The link is designed to relay data at over-the-air rates of 20 kbps or 250 kbps over distances of up to 1000 m" which is still a bit too short of Earth $\endgroup$ May 23 at 21:16

14$\begingroup$ Indeed. Note that my answer is a bit tongue-in-cheek, since of course Perseverance also (usually) does not communicate with Earth (although it can in a pinch) but with one of the Martian relays. They're not quite as far away as Earth, but still orders of magnitude farther than 1000m. $\endgroup$ May 23 at 21:24
