[Bug]: [PR] Negative Guidance minimum sigma does not work with SelfAttentionGuidance Integrated built-in extension

[playlogitech]

Checklist

• The issue exists after disabling all extensions
• 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
• The issue exists in the current version of the webui
• The issue has not been reported before recently
• The issue has been reported before but has not been fixed yet

What happened?

generation crashing when NGSM enabled

Steps to reproduce the problem

increase negative guidance minumum sigma, I used 0.4

What should have happened?

generation crash with error

What browsers do you use to access the UI ?
