Air blowing, but no cool air.

My AC unit is 5 years old (mfg dat: 1/1/2021, installed spring of 2021).
Yesterday, we realized that it was abnormally hot in our house, like AC set to 70, but thermostat was reading 75. Outside was maybe 80⁰ as a high.
Air blowing out of our vents at normal speed.
Outside unit fan is running as normal, and fast.
Just no cool air coming from our vents.
We replaced the filter, made sure it was clear around the outdoor unit, turned our system off and set fan to on overnight to thaw in case anything was frozen.
Nothing helped.
Not sure if this is important, but..: Whenever our hvac turns on, our lights do the smallest of flickers (always has), but they only do it when it turns on/off. However, when we turn our system on to see if whatever we did (by the slim chance) worked, our lights flicker every 60 to 90 seconds.
The air coming through the vents still isn't cold. We have window units to help for the time being, but would still like to get our system back to functioning correctly.
Could it be the capacitor? Could it be something else? I have 3 young kids, and we live in the south where temps get offensively hot.
Help.
