Got the same error message when going to that location with another character on PvE-C official server 1818. Game crashes to desktop as soon as character loads in.
Fatal error: [File:C:\B\tech_exiles\code\Engine\Source\Runtime\CoreUObject\Private\Serialization\AsyncLoading.cpp] [Line: 6738]
LoadPackageAsync failed to begin to load a package BP_Event_Q4_2021_1 because the supplied package name was neither a valid long package name nor a filename of a map within a content folder: ‘’

So north of Dagon’s Eye on the river bank= Crash with this error message. On multiple characters on 1818. There is an exotic base there, but looks like things I have seen before. Anyway, anyone who goes there might experience the same thing. I did a reboot and had Steam verify the integrity of my game files. I can play my characters on other servers with no problems. All day.
I guess I missed your format for bug reports. It used to be automatic. I have to go. I will try to update with your format tomorrow.
