One Page problem

Hi Creatio Community,

I'm running Creatio 8.09 on-premise (localhost, Windows + IIS + PostgreSQL) and experiencing an issue where I cannot open the application in multiple browser tabs simultaneously.

Here is what happens:
- First tab opens and works perfectly fine
- When I try to open a second tab, it gets stuck on the loading screen indefinitely
- The second tab only loads after I close the first one
- The same issue occurs in incognito mode and across different browsers (Chrome, Edge, etc.)

Thank you in advance for your response!
