I've been using Ninja & Interactive Brokers for years but today - almost none of the charts loaded on my Windows 11 desktop.
I even created a new workspace (no other workspace active) and tried to load a single daily chart with no indicators and it's still stuck at "Loading..."
When I checked the log, I see this:
"IB failed to process server API request: 'Error processing request.-'bS' : cause - Duplicate ticker ID for API historical data query'
I managed to fix it eventually by activating Tools > Database Management > Repair DB
That worked for a while.
I came home and tried to run it again and this time, the Repair DB trick does work.
I thought it's OneDrive causing the problem so I turned it off for Documents, uninstalled Ninja and then reinstalled but it's still not working.
I suspect it's "Windows thing" since on my Windows 10 laptop everything is OK but even after installing the latest Windows update, I couldn't get my desktop Ninja to work

I even tried using NinjaTrader in safe mode but even 1 basic chart (virtually no indicators) failed to load.
Update: the funny thing is that I did everything I could to fix the problem; reinstall, reset database etc. but nothing worked. Now when I woke up this morning, I decided to fire up Ninja and try again and this time the chart loads!! I can't figure this - anyone, any clues?? However, once I load a daily chart, the chart loading got stuck again

Update (3 Feb 2023)
I don't know why the difference but when I uninstalled TWS and then install the Java Runtime (JRE), it got fixed.
Update of the update (6 Feb 2023)
It's so maddening - I opened up Ninja this nice Monday evening (I'm in a different timezone) and it's again - not loading....

Any clues folks? I've tried "everything"
==> After trying so many things, I had to downgrade to TWS 981.3i - hopefully this version holds out until you guys have a fix
