I have an AAWP website that also got hit at the end of July with one of the PR updates. The freefall looks just like your GSC graph. BUT it recovered on 9/26 when the core update finished rolling out and not only did it recover, it gained 120% more traffic out of the blue. I didn't do much in that time period either other than just general posts updates and fine tuning things. I sure as hell wasn't going to add posts or spend a bunch of time when google basically tanked the site. Some posts I have 5-10 AWP links on are getting good traffic again, so AAWP is not the issue.
So I just waited and the core update rolling out flipped the switch and traffic is now at all time highs (with AAWP). Honestly I don't think there's anything you can do to get the traffic back until Google roles out the next major update. Fine tuning your website now may help with that when it comes, but don't think you're going to just change some things here and there and all of a sudden traffic shoots right back up. Google AI tanked your site, and the only thing bringing it back is google AI unfffff'ing itself to get you back to where you should be. I think you have to WAIT until the next major update to see a reversal. If your site is generally good, and I would assume it is since your impressions and clicks growth look decent, that this is solely on Googles end, not yours.
So at this point decide if it's worth your time to spend on it ,or focus on another endeavor, until Google makes up their mind.
