Issue with opening saved files

I have been using Qupath for some time now to generate H-scores for a number of stains.

I am encountering the following problem: When I try to open a previously saved file (project.qpproj), I get the following message: “Qupath has encountered a problem, sorry If you can replicate it, please notify a developer. Java.lang.NullPointerException”. I get this message with certain files but not with all of my saved files. These files are saved under a common drive. I have also tried to copy the file and open it from my desktop, but this hasn’t helped either.

I would appreciate any input on the above issue!


Hi @Valia, can you please specify which version of QuPath you’re using?

Also, when you see the error can you copy & paste the contents of View → Show log?
