Project opening Issue

[thanuship (Thanushi Perera)]

I get a error message when opening a new project or existing project in UiPath Studio. Is there any solution for that? I tried uninstalling the studio for several times but it doesn’t work on my machine.

23.10.0+Branch.master.Sha.e038c5a32a4f890ba12a3c04ac465dc8811521e0

Found invalid data while decoding

Hi, @thanuship

If the first suggestion doesn’t work

try clear these two folders:

C:\Users\Thanu Perera\AppData\Local\UiPath\.cache
C:\Users\Thanu Perera\.nuget\packages

feel free to make a backup for both before the clear

Cheers

Projects created with newer versions of Studio might not work with older Studio versions. Read more about Studio - About Automation Projects (uipath.com)

[thanuship (Thanushi Perera)]

Thankyou for the reply. The issue is even I cannot open a new blank project like below

[Nguyen_Van_Luong1 (Nguyen Van Luong)]

You can’t create a new Process
that’s right?
could you please show dialog error?
regards,

[thanuship (Thanushi Perera)]

This worked for me. Thank you for the support. Do you have any idea of why it happens?

[thanuship (Thanushi Perera)]

I got fixed it out. Thank you for the support

[thanuship (Thanushi Perera)]

I had the issue when creating a new project. I got fixed it out. Thank you for the support.

Hi @thanuship

Glad to help

It seems like corrupt/conflict dependencies. When you remove the mentioned folder, the dependencies packages will download again resolving any conflict.

Kindly mark as solution to help others with the same issue.

Cheers

[thanuship (Thanushi Perera)]

Noted. I will mark it as a solution.

Thank you
