Hello there and thank you for reaching out, please try the following and let us know if the issue is still present:
1) fully close the Launcher
2) Delete this file "C:\ProgramData\Epic\EpicGamesLauncher\Data\EMS\current"
3) Start the Launcher
Check if Twinmotion Community Edition is available to download and launch inside the Launcher.
This is the same as a TRial so you do not need to pay.
Thank you
MC
