Workflow cannot be displayed when switching tabs

### Prerequisites

- [x] I am running the latest version of ComfyUI
- [x] I have searched existing issues to make sure this isn't a duplicate
- [x] I have tested with all custom nodes disabled ([see how](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled))

### What happened?

When I am running a workflow, switching the workflow tab will keep the interface blank, even if there are no tasks running, it still cannot be displayed. I conducted the following tests
1. Disable all third-party plugins, problem persists
After the task is completed, there is a probability that the corresponding workflow will be displayed, but others will not be displayed
3. It seems that the probability of occurrence is relatively high in some particularly performance intensive scenarios

When I switch, the console will display the following information:

### Steps to Reproduce

1. Run a performance intensive workflow (such as running 4K images and generating videos)
2. Switch between tabs that have already been opened, switch back and forth a few times, and there is a high probability that it will appear
