I have a working branch here: https://gitlab.winehq.org/DarkShadow44/wine/-/commits/remarkable
Still needs some more work though, not sure how the memory management between those two interfaces works.
I tried out your working branch, and got the same crash as reported in 57553 on 10.0-rc2. I've attached a backtrace for that crash, which seems to place the fault inside the PE version of qnetworklistmanager.dll, as called by qt6network.dll. Since the reMarkable desktop application uses Qt, I'm guessing those are the DLLs for the version of Qt that ships with the client application installer.
