Close all tabs in browser and reopen the Qlik sense hub after 3-4 mins and than check. This will sovle the problem for now.

After that check in QMC how many Qlik Engines are available to use and how many concurrent session are going on in QMC.

Thank you.

I did what you've suggested - but the issue still persists. I cleared the cache, and even reinstall the SW (I'm using the desktop version). i can see the last analyzed sheet but i can't access the data manger.

Any other suggestions?

Check if multiple  copies are opened or not. Also, restart the system.

Still persists - after reinstalling the SW from scratch...

I've found the solution!

It looks like the new installation is somehow connected to the old registry.

The solution was to install it using the customized installation and choose a different name for the Qlik folder when it is created (Qlik_2 for example). 

thank you for your support.
