TPS631000:PSpice for TI

Part Number: TPS631000

Tool/software:

I am currently experiencing an issue with PSpice for TI. When I try to run a simulation, the simulation screen remains stuck on "Initializing" and does not proceed.
I suspect this may be related to a previous simulation that ran too long, and I was prompted to choose whether to stop the old one and start a new one.
Could you please advise how I can resolve this and get the simulation working again?
