Ok, are you saying that this happens with a fresh download of the project files too? Or have you made some modifications? As this doesn't happen on my end. Are your runtimes also up to date?
Fwiw the error itself refers to code trying to treat something that isn't an array, as an array. And if it's happening when it becomes one of your character's turns, chances are it's happening when trying to build the action menu for that character. Which might mean you've added or changed something in gamedata for that character (or perhaps an action) but accidentally affected the datatype or missplaced a comma or something similar?
Unfortunately I'm low on ideas as I simply cannot reproduce the issue on my own end without changing the code intentionally to do so. All I can really suggest is that you place a breakpoint somewhere inside the DoTurn() function in oBattle's create event, just after the point where it has decided that it's a player turn (like the if (_unit.enemy == false) line). and run debug mode. Then when you hit this breakpoint use the Step Into Function Call button to progress one line at a time until the error occurs which might give you more clues. As your error as posted is struggling to isolate the problem line.
Hello again! sorry to bother you, but I believe your bug may have been related to this issue that was reported recently. Was HTML5 the platform where you were hitting this bug? If so and you get a spare moment would you be able to either get the latest files or implement the fix mentioned in that post and let me know if you still get issues in the browser?

No dice, I was using the GX.games browser launcher, it might just be that system it seems pretty buggy. But I'm running into another issue with the regular launcher, after yours and the slime's turn it does this:

That, fortunately is the exact issue mentioned in the post above. Will look into the GX games thing but with the windows launcher if you implement the fix in the link in my previous post, or get the newest files it will fix that particular error. The mention of " if (_option[0] == "Attack") return 99;" is the giveaway.
I got an error when I interact with the slimes:

You seem to have a mix of versions here for some reason. Line 37 of your oBattle creat event is from the new version, but the line in your slime collision event is from an old version.
Edit: i've also confirmed that the most recent version also works properly in Opera GX, so if you're still hitting errors this is a problem with your project specifically.
