Failed to instantiate type com.diffblue.cover.logging.appender.CoverRollingFileAppender

I am unable to create tests using diffblue cover, above error is the issue…please find the attachment

Hi Arun,

Thank you for reaching out
From the picture we are unable to see the root cause of the issue.
Is it possible to upload the whole support log? - this will be found in the same directory as you have seen this user log (Log files | Diffblue Docs)
With the support logs we can have a look to see why this behaviour is occurring.

Thank you,
Jane @ Diffblue
