Hello again.
I've gotten a chance to start to look into this for you and I need a couple of questions answered before I can continue to troubleshoot.
I don't see the dual wield plugin in your list. Are you using that? You must be since the crash error is coming from the dual wield extension, which throws an error if you try to use it without the dual wield plugin.
I can't duplicate the issue with mhpry and ohpry and xpt not showing up on that screen myself, but since I can't see where you're loading the menu extension in the order, I suspect it's being overwritten by the YEP_StatusMenuCore plugin, since I can't see that one either. Load StatusMenuCore before the menu extension and that should sort that problem out.
Looks like the crash that is happening is somehow related to splitting the hit and crit params for dual wielding. I am familiar with this particular error from porting the block plugin to RMMZ, as the extraparamformulas plugin features are included in one of the default VS plugins for MZ. I fixed a similar crash in MV related to block rate already, so I suspect the issue is caused by something similar. I'll get back to you on this shortly.
edit:
Okay, I can't duplicate the crash at all, but looking at the line the crash is coming from, I can see what the problem is, though not how it is caused.
In a fix I posted in v1.39 or v1.40, I fixed an issue where people using the extraparamformulas plugin would see incorrect values for hit and crit when showing the main and offhands. This fix expressly assumed that the scene would always have an actor in it, because if it didn't, how would it be displaying any information at all? Well apparently in some (unknown to me) case, this very thing was happening, so it was causing that crash error when it tried to draw the mhhit value for you.
I have posted a fix that should resolve this.
