error: perspective switch job in ccs v5.1.0.9

Hi,

a few days CCS v5.1.0.09 began to show an error when I try to launch debug session:

and I cannot get the debug session menu appears, i.e., run, stop, pause, etc.

I am using lcdk6748 with xds100v2.

If someone can help I will appreciate.

Thanks in advance,

julian
