No Invoke Workflows are working

I’ve a number of Sequences I’ve created where I’ve invoked it to make it more managable.
Recently reinstalled UiPath due to issues whereby very basic activities werent being recognised - despite having the latest packages available.

After a fresh install that was overcome, but now it won’t invoke any work flow.

I created a test sequence showing a message message box and attempted to invoke it. Lo and behold I get this error:

25.0.157-cloud.18912+Branch.release-s157.Sha.7489f58f146d342879812d8004994f9c67c3982f.7489f58f146d342879812d8004994f9c67c3982f

I’ve deleted the Project.json, loaded it back up again and recompiled.
Even wound the UiPath.System.Activities to 24.3.1 but that doesen’t work.

@steve1977beyond,

Try switching to stable enterprise version of Studio that is 2024.10

2025.0.157 is the community version

Try to toggle the option Separate Runtime Dependencies under project settings and save the project. Open again and give a try
