I am getting cannot access closed pipe issue randomly.
For example , when i am opening the Xaml or running the file in uipath
@divya.rajendiran There is one more thread already created for this question. Refer below link hope this will resolve your query.
Hello @divya.rajendiran
If you are facing this while performing some particular action or activity. Suggesting to update\downgrade the package version to a stable one.
Then try to execute again.
- Are you getting this error for only this file or other xamls as well
- Also, can you share the screenshot of the activities that you use in this xaml
i am getting this for mostly all the Xamls. Suddenly when opening the files or even while executing the Xamls
@deepak.rai6 i checked that as well Deepak. That didnt resolve my issue 
Hello @divya.rajendiran
Did you tried creating a new project and verified whether you are getting the same issue for other projects also??? If no, plz have a try and update here.
For the current project can you take a backup and delete the project.json file and then try to reopen again in studio.
@Rahul_Unnikrishnan yes, i did it. I am getting that error for all the projects
Still i am struggling to resolve the issue. is there anything with package version ???
@divya.rajendiran as it is affecting all the projects I don’t think it’s a package issue. Can you try installing a new copy of uipath?
Also, is UiPath installed to any folders which are having any access restrictions?

is there any possible solution for this error. I am using Studio 22.4.4 and while opening any xaml i am getting the below sample error.
I have tried creating different project in different location, tried updating the package. Still it is giving same error.
