BTT Crashes When Creating a Group With Backslash in Name

I created a conditional activation group called 'test\'. I didn't change the conditions from the default values.

When i clicked save, the BTT immediately crashed.

Now the group appears in the list of groups. Whenever I select it, BTT immediately crashes again. (Because of this, I don't think I can delete this group.)

As far as I can tell, everything else is functioning normally.

Here's a screenshot:

This happened on Version 3.219

The problem persists after restarting

The crash log is too long to post here. Here is a link.
