[BUG] Cannot add nodes to workflow - interface becomes unresponsive

[ktee4706-hub]

Bug Description:
The workflow editor interface stops allowing new nodes to be added.
Clicking the "+" button or attempting to drag nodes from the sidebar
has no effect. The interface appears responsive (can click existing
nodes) but adding new nodes is completely blocked.

This bug is recurring - it has happened multiple times during the
same session, requiring frequent restarts.

Expected Behavior:

• Should be able to add nodes by clicking "+"
• Should be able to drag nodes from sidebar
• Interface should remain functional throughout session

Actual Behavior:

• Clicking "+" does nothing
• Dragging nodes has no effect
• Cannot expand workflow
• Only option is to restart n8n

Steps to Reproduce:

1. Create or import a workflow
2. Work on the workflow for 15-30 minutes
3. Import/test multiple workflows
4. Try to add a new node
5. Interface stops responding to add node actions

Frequency:
Happens repeatedly - multiple times per hour of use

Environment:

• n8n Version: 2.4.6 (Self Hosted)
• Installation: npm install -g n8n
• OS: Windows
• Browser: [Your browser - Chrome/Edge/Firefox]
• Database: filesystem

Impact:
High - Makes it impossible to continue working, requires restart

Console Errors:
[Press F12, go to Console tab, copy any errors you see]

Workarounds Tried:
✗ Browser refresh (Ctrl+F5) - doesn't fix
✗ Clear cache - doesn't fix
✗ Different browser - same issue
✓ Restart n8n - temporarily fixes but bug returns

Additional Context:

• Bug occurs after importing multiple workflows
• Happens more frequently after testing workflows
• Affects both new and existing workflows
• Other n8n features still work (can execute workflows)
