Hello,
Apologies for these issues. There was an issue with the Twinmotion 2024.1.1 build in the Epic Games Launcher, so we have rolled back to the 2024.1 version.
For anyone who had the 2024.1.1 build installed and is encountering crashes, please uninstall this version of Twinmotion and contact support by submitting a case at https://twinmotionhelp.epicgames.com/s/case-community-page for further instructions.
