I also experienced this kind of behavior while developing the process or when reopening the process it will take some to load. But after some time it will available to to develop the process.
And we need to make sure same project should not be opened any other tabs.
And also install latest version of assistant and if you are already have the latest version log out and login and clear all the cache from the browser

yup… UiPath shouldn’t have launched a web version which is tbh, crappy and buggy!
advice : always use desktop variant

Hi @balkishan
Yes, this is a known issue with Web Studio. “project loading / read-only mode” usually happens due to sync or session issues( even if the connection shows green).
You can give a try on the following
Ctrl + Shift + R)Also, I noticed the version shows “Non-compliant” : updating dependencies and republishing can help.
If it still persists, open it once in Desktop Studio and republish , that usually clears the issue.
UiPath is actively improving Web Studio, so hopefully these issues will be smoother in upcoming updates.

so many, bugs , it is not really a user friendly 
@balkishan : I understand it can feel frustrating when these issues come often. From experience, this is usually a session or sync glitch rather than a real connection problem.
Recommend to give a try on the following
If it still doesn’t work, just open in Desktop Studio and republish , that normally resolves it.
Studio Web is still evolving, and UiPath is continuously improving it, so we should see better stability soon
