Baldur's Gate 3 Not Installing Properly

I'm attempting to install BG3 from GoG on my Steam Deck. I have the launcher working (installed dotnet) but the launcher says there's a files mismatch. I know the mismatch is coming from a series of "Game.pak.tmp" files (numbered, for example Game.pak.tmp1, Game.pak.tmp2 and so on).

I have reinstalled, updated, verified/repaired and these files are always downloaded and never merged into the Game.pak file. I'm not sure what else to try here.
