Replace the UPF (rename the current one or moving it out of the
folder).
Restore MicroStation to Factory defaults

Menu item: CWorkspace > Preferences > Operation: "Uncheck "Compress File on Exit" (workaround: manually compress).

Other things to try (all versions):

-Bad Resource File

Remove RSC files from the MS_SYMBRSRC + MS_FONTPATH and replace one at a time until

-File Corruption

Detach ALL references and reattach them, to narrow it down.
