In response to post #108816338. #108956753 is also a reply to the same post.
Same problem, but some additional info:
I am trying to install on Linux - the steam deck to be precise.
LW install works fine, also the linux install script from LWR says it works, but when starting a new game, this issue appears. After you select a starting country and the mission load screen, you only see the hologlobe from the xcom HQ.
I tried with the install_linux and the install_linux2 script but both show that issue. So it seems the handover to the tactical gamemode is not working correctly for whatever reason.
