[Bug]: after sleep mode Forge freezes the computer

### Checklist

- [X] The issue exists after disabling all extensions
- [X] The issue exists on a clean installation of webui
- [ ] The issue is caused by an extension, but I believe it is caused by a bug in the webui
- [X] The issue exists in the current version of the webui
- [X] The issue has not been reported before recently
- [ ] The issue has been reported before but has not been fixed yet

### What happened?

When my computer goes to sleep mode with Forge open, doing anything in Forge after it wakes up freezes the computer.
If instead I close Forge and open it again however it's ok. So going to sleep mode must be doing something to Forge's memory.
This does not happen with Automatic1111, only with Forge.

### Steps to reproduce the problem

1. Open Forge
2. Let the computer go to sleep mode
3. Wake up the computer
4. Try to generate anything

### What should have happened?

Not freezing and working as usual.

### What browsers do you use to access the UI ?

Mozilla Firefox

### Additional information

_No response_

Begin by reproducing the reported sleep and wake sequence with Forge open, then inspect the console behavior when generation is attempted afterward. The report names no source file or test; done means Forge continues generating after wake without freezing the computer.
