Run Report Second time gives error in RTC

Hello Experts,

Today I made a Customized Report in RTC Which Run Successfully in Classic and in RTC As well.
I check this report with Run Command DynamicsNAV:////runreport?report=50008 It Runs Successfully with default
Role tailored Home Page and then i close the Report , Role tailored Home page still open and then again i run the same report by Run Command DynamicsNAV:////runreport?report=50008 then it gives me Error as Following

Then I have to close entire RTC and re-run the report.

Why this happend ? How to check and Solve this?

Thanks in Advance.
