The first detailed repair tutorial online
1. Preparation
You need any editor that can edit DB files. If you don't have one, you can download DB Browser for SQLite (choose the no-installer portable version).
This tutorial is written for DB Browser for SQLite; other editors work similarly.
Extract the archive and open DB Browser for SQLite.exe
Exit G HUB.
2. Open G Hub settings.db
Press ctrl + O - type into the address bar: C:%homepath%\AppData\Local\LGHUB\ and press Enter.
First right-click settings.db, copy it, and paste it to any safe location (backup).
Select the file settings.db and open it.
3. Open the saved configuration
Switch to 浏览数据（B） and click the cell for the file with id 1 (displayed as {...).
The data will be shown in the window on the right. Select that window.
4. Remove the erroneous data
Press ctrl + F and search for the keyword rainbow.
Delete all rainbow six siege entries under APPLICATION_NAME_DESKTOP. In the end it should look like []. If there are other items that are not Rainbow Six, make sure the last entry is not followed by ,
5. Write changes
Click the _date_created cell corresponding to id 1. You will be asked whether to save; click Save.
Then click 写入更改（W） at the top, and close DB Browser for SQLite
6. Restart G HUB
Restart G HUB from the Start menu. Normally it won't report data corruption; if it does, let it repair itself, and if it can't be repaired, replace the file with your backup.
If you can't figure it out, look up JSON syntax or ask ChatGPT.
7. ENJOY GAME
Thanks to G HUB not switching profiles - Reddit for mentioning the solution of repairing the config database.
However, the original post is too vague and doesn't give detailed repair steps.
Which intern at G HUB wrote this damn bug? The GUI is even completely invisible.
