Don't forget that dBm is a power level expressed as the base10 logarithm of the ratio of the measured power compared to 1 mW. Your signal level is 30 dBm or 1000 times weaker than mine, and the link quality is definitely worse.
To come closer to your signal level, I set up a test with moOde 9.2.1 on a Pi 3A+ located two rooms away from my Access Point, apx 50 feet through 2 doorways as the bird flies. The WiFi connection is in the 5 GHz band.
I streamed a Jazz Groove channel to it via Airplay from an iPad for two hours without a hitch.
From iwconfig
From ifconfig
In this test, my reported signal level is 5 dBm or a factor of about 3 times stronger in power than yours. My link quality is better. Out of roughly 1 million received packets, only 6 were dropped. There's nothing remarkable in the logs.
I would suggest you try moving your Pi and your access point closer together, at least temporarily, to see if that "cures" your AirPlay problem. That will help you decide what needs to be done. (In one extreme case, I have used Powerline Networking as a way to get around poor WiFi communications without physically stringing Ethernet cable.)
Good luck!

In my case the raspberry Pi the status of the Link Quality is 51/70 and the Signal level -59 dBm. I assume that is a medium quality signal strength. No as good as yours but operational.
