ID 457946 - Sequences from closed Nuke Studio/Hiero Projects can reappear when changing Workspaces

Problem summary:

Sequences from closed Nuke Studio/Hiero Projects can reappear when changing Workspaces

Customer reported version:

Hiero 14.1v4

Customer reported platform:

Rocky 9

Steps to reproduce:

1) Launch Nuke Studio and navigate to File > Import File(s)...

2) Select a file to import, and create a Sequence by dragging the footage to the Timeline.

3) Navigate to File > Save Project As... and save the Project (optional)

4) Close the Project by navigating to File > Close Project

5) Switch the current Workspace to Conforming, Editing, Timeline, or similar and observe how the previous Project's Sequence is now visible.

Alternative steps:

1) Launch Nuke Studio and open an existing Project.

2) Close the Project by navigating to File > Close Project

3) Switch the current Workspace to Conforming, Editing, Timeline, or similar.

Expected behavior:

Changing the Workspace should not retrieve any information from closed Projects.  

Actual behavior:

When closing a Project and switching to a different Workspace, it's possible for Sequences from the closed Project to be loaded. This can create situations where the current Project is empty but the UI is still populated with information (pictured below), or where additional Sequence View Panels are unexpectedly added to a different Project:  

Workaround:

No known workaround at this time
