Bear with me, while I try to understand this, but it looks like b?branch sets up some type of temporary buffer, and b(>resolve) try to “flush” that buffer.

Just deleting the b(>resolve) I’m hanging on and replacing it with ff gets a little further, and what I’m thinking is these two b(>resolves) and the two b?branch that come before them have something to do with the children, NVDA,Display-A and NVDA,Display-B. Maybe something to do with display detection, or the set-mode command.
Here is the result of skipping the last b(>resolve):

Get-mode, show-mode, and set-mode are called twice, I assume once for each display node, so something is going wrong with NVDA,Dispaly-A/B, I just don’t know what it is.
Something b?branch sets up, but b(>resolve) can’t resolve?
