@GOURABKETAN did you find out the solution?.
@azmathullashaik No support ticket appears to have been logged for this issue.
The error encountered is a NoClassDefFoundError, which means a class that was available at compile time is not found at runtime.
The class that is not found is a generated class, which means it is created by Pega during the rule resolution process. If this class is not found, it could mean that there is a problem with the rule resolution process, or that the class was not properly generated.
To resolve this issue, you could try clearing the cache and restarting the system to force Pega to regenerate the class.
