Hi @TruptiF
This is a common issue affecting many PDI users at present.
ServiceNow has acknowledged it is having problems with its PDI infrastructure. It says it's working on this, but hasn't provided a timeframe for a fix.
Your options are:
1. wait for the problem to be fixed, or,
2. release your instance, take a new one, and hope it works. If you do this you will lose everything that's on your current PDI.
