I've been struggling with this issue for some time, and I believe that it started sometime around OpenWRT 22.03, but unsure of which release I moved to. Device is WRT1900AC v1, was running 22.03.2. Now running 22.05.0-rc1, issue remains.
Symptom is that wireless clients will have a working connection, then the connection stops, IP on client is a 169.x.x.x address. Turning off wifi and back on restores this for a time. Windows laptop, iOS devices, same issue.
Thinking it was related to the wifi, I disabled the radio in the WRT1900AC and set up a separate access point for wifi, issue remained. Separate access point is not set up for DHCP, that remains with main WRT1900AC router. Wired systemswith static IPs have no issues with loss of connection.
I found some postings regarding mvebu issues which caused no further builds of 22.03, kernel 5.15 supposedly fixed these, but updating to 22.05-rc1 hasn't helped my situation and so I may be seeing a separate issue here. I'm not seeing anything unusual in the System logs on the router.
let's see your config.

I've reverted back to 21.02.7, issue appears to be gone, so I'm assuming some bug crept in after that and was still present in 22.05-rc1. Will continue to monitor.
I was going to file an official bug report, but the form requires some exact output from the console for the version having the issue, and I've already wiped that install... LOL I guess if I test with rc2 (and take down the family internet again) I can do a bug report then.
