Hi Badwolf71, welcome. I’m just another player. Before accepting any free advice on the internet, please ensure your computer files are backed up and that you feel competent to make changes to files within your system.
To verify your files via Steam:
Steam | Library -> Right-click Conan Exiles
Click Properties, select the Local Files tab
Click Verify Integrity of Game Files…
There is another item that used to cause issues 6-8 months ago, but it will require viewing and editing a .ini file, which no responsible tech would post without first receiving consent, and assessing competency level from you. If Verify process has not cleared up this Fatal issue and your broadband connection is adequate, it is sometimes more advisable to uninstall via Steam and then reinstall.
