Update to #98756

Hello Sonja,

Thank you for the additional details and screenshots. Before we continue, I want to point out that I still don’t yet have the key information I originally requested, and I’ll need it in order to diagnose this properly.

I still need:

• Your Output.log taken immediately after the error appears

• Confirmation on whether this happens with one Brain or with all Brains

Since you’re on TheBrain 15, the easiest way to get your log file is:

1. Click the three horizontal lines in the top-left corner of TheBrain
2. Select Help
3. Click Open Log Directory
4. Send the Output.log located in that folder

If for any reason that method does not work, you can also find the log manually here:

Windows

C:\Users[your username]\AppData\Local\TheBrain\Logs

macOS

~/.TheBrain/v9/Logs

(Finder > Go > Go to Folder > paste the path above)

Regarding the errors you shared:

The blank screen and the exceptions you posted typically mean the app was unable to fully initialize the UI. This can happen if:

• the local copy of the Brain did not finish downloading

• the local Brain data became corrupted

• the MetaDB cache is in a bad state

These are usually straightforward to fix, but I need the log file to determine which of the three it is.

Once I have:

1. the Output.log
2. confirmation on whether other Brains open normally

I can guide you step-by-step through the correct fix.

Best regards,

John
