When logging in to P6 Professional Cloud, data and tables load initially but then the P6 Professional splash screen hangs for 20-30 minutes, then the following error is displayed:
TCVirtualTable.ExistInDB: table=(User Session), sql=(), Exception=()

The issue can be reproduced at will with the following steps:
1. Login to P6 Professional.
2. A "Loading Data" progress bar displays briefly.
3. The P6 splash screen hangs for 20-30 minutes.

This issue may also occur in a P6 Professional Standalone environment, but without the error. The condition is that the splash screen will hang for 3-5 minutes, which the customer may report as a performance issue.
