Second POL Crashing, No Error Message

Reinstalled FFXI on a new SSD. Then downloaded windower and the "make the game look great" stuff from the Nextgames video (2022 version). I had all of this before with no issue.

I boot up FFXI via windower and then a second POl for my mule. Log into both and one just crashes after a few seconds. NO error, just poof. Then, if I try to start another POL via windower, it just boots up POL without windwer. If i wait a minute, it will start up in windower and I get both logged into the game. However, after a minute or two, one crashes, again with no error or warning.

Any thoughts? This is very frusrtating!

Is UAC on, are you giving windows permission launching the 2nd. Are you crashing in a specific area. Did you properly install the game and not just copy files over. Some out of date addon. Are you using a new UI mod (if you're using one). Are you sure you only have one version of XI installed.

After recently going through random crashes I'll take a stab in the dark here:

Do you have an Intel 13900 (K/F/KF) processor? If so, there's a decent chance you've got a bad core like I do, and you'll have to either manually set the affinity to avoid Performance Core 4 (most say that's the one, worked for me I didn't process of elimination it), or use ProcessLasso to avoid that core entirely.

If not, download MemTest86, make a bootable USB from it (comes with instructions), and boot into that and let it do the full scan on your memory for a few hours.

If that comes back clean, then you'll have to go down the list of stuff other people will suggest like disabling UAC, enabling DirectPlay, test without Windower, etc.
