ERROR_MUI_FILE_NOT_LOADED

ERROR_MUI_FILE_NOT_LOADED means a caller expected a MUI resource entry that the Windows resource loader had not loaded. This can happen when the requested language resource is absent, invalid, or not associated with the language-neutral file.

What to check

Confirm that the requested UI language has a deployed .mui file in the expected language subfolder.
Check for an earlier MUI validation or locale error; this code is often a later symptom.
Restart the application after repairing or redeploying resources so it rebuilds its resource-loading state.
