Can't open PoE since 3.10 launch patch

Update: As of May 29th, it finally works. The fix was not on my end.
What this looks like:

I've reinstalled the game at least 5 different times since it broke(3.10 launch 22 days ago).
Over 2K hours since 2013; this hasn't happened before.

• Worked right before the 3.10 patch and it's never opened since.
• The Standalone works(after manually restarting the launcher 15 times so it'd actually download properly), but I won't be using the standalone regularly, I'm only playing on Steam.
• Not stuck in an update loop, which many people had happen.
• --nopatch doesn't help, no launch options currently set.
• Steam running as admin.
• Running the game executables as admin by default doesn't help.
• Switching between Steam client beta states doesn't help(this redownloads the client each time as well).
• Validated game files multiple times through Steam & Content.ggpk checker (no issues found)
• Reinstalled the game multiple times over the past 3 weeks, also cleared dead caches left over in Documents.
• Cleared Steam's download cache multiple times and switched download servers multiple times, also verified files afterwards.
• Rebooted PC and Steam client multiple times. The above required multiple client restarts.
• A couple times I attempted to launch PoE, the "Steamworks Common Redistributables" were downloaded before launching, which are required to run PoE. I went through all of installers in all of these folders and "repaired" when I had the option to. Still no luck.
• Win10 x64 v1909 latest public build, also updated to v2004(Insider build 19041.153). I then rolled back to v1909, did more updates and verified Windows file stability. Nothing helps.
• Nvidia RTX 2060, AMD FX-8350 @ 4.3GHz, 16GB DDR3 1866MHz RAM, 1TB SSD
--> Used to get 200 FPS in-game on high settings.
• Latest drivers for everything, tried multiple Nvidia drivers and DDU.
• No firewalls or other background processes should be interfering with PoE or its connections. With that said, my "hosts" file is also clean.
• No other software or game on my PC has any issues like this, or in general.
• There's no crash dialogue boxes and the log files are blank.
• I copied over files from the Standalone installation to Steam's installation with no luck. (After all of the above)
I'm very tech savvy, but I can't get anywhere here, nothing leads to this being on my end. It's always possible that I've missed something.

Updated after testing the standalone and more. (Not resolved)
Also the little I did test on the Standalone, even Twilight Strand made it obvious that performance is much worse this league(hitching), but that's for another topic.

This is on page 32 now and I've posted about it in multiple places since launch with no sign of GGG acknowledging the issue. I get it, people spamming minor issues, but c'mon, the game's been straight-up broken for weeks. I'm not the only person getting this and I've tried everything under the sun that is remotely worth doing to solve something isolated to 1 game caused by 1 update.
As I said, I'm not using the standalone, so I'm skipping this league and at this rate I wouldn't be surprised if it was unplayable next league too.

I'm having this exact issue still. So if it was a solution on their end, it didn't fix it for everybody.

how did a 3.10 thread matter to 3.11.1??? Open a new thread for you unrelated bug
