This error is caused by a bug in the Xbox app patching system. It will need to be fixed by Microsoft - in the meantime, the current workaround to download update 2.4.5 is to uninstall and reinstall the game. We understand this is not an ideal solution, but it is the only known workaround while we await a fix. More details here: Microsoft Store/Xbox App Patching Issue (aka Error 0xD05E0108)
To add to it:
Update June 24, 2021: As of version 2.4.6, the game should no longer conflict with 11th-gen Intel processers and the below workaround should no longer be required. Please let us know if you continue experiencing this issue.
Some players have recently reported the game not launching after…well, launching it. Check your CPU; if you have an Intel 11th Gen CPU, you may be one of several people reporting problems, and you may be able to work around it with the following:
Game frequently pauses/hitches when trying to move with keyboard/mouse, is fine when using a gamepad or not moving
It’s unclear whether or not this is tied to the Gamepass version of Conan Exiles, but Winny has suggested that this issue may be related to Razer peripherals and their driver app.
Try exiting the Razer Central app and see if that works.
An issue causing frequent freezes during teleports or in certain spots of a map on Game Pass PC has been resolved as of the 2.4.5 Update.
This issue should now be resolved as of a new Steam update released today (June 3, 2021). Please update your clients and let us know if you continue to have any other issues.
Further edit: This issue appears to still be present in the GamePass PC version. This will be patched out as soon as possible.
