Hi,
There is a JIRA for this issue (Opened since UE 4.26 -> UE-93120). Here the comment on the JIRA:
`[DetailCategories], [GameplayTagWidget] and a few others take up the majority of space in EditorPerProjectUserSettings.ini
There is no method of cleaning up entries for things that no longer exist.
There are 10k-500k entries that cause saving of the .ini to take 2000+ms.`I’ll link this ticket to the JIRA. In the meantime, manual cleaning will be required to erase old data that do not have value there.
Regards,
Patrick
