I am writing paper with LaTeX tools in Sublime Text 4 in Windows 11 platform. Occasionally, a strange phenomenon occurs where a new file page shows up in Sublime Text itself with only one comma in it. As is shown in the following image. I don't know why it happens and what's wrong with my Sublime Text. Anyone also suffers this and helps me out? Thanks!
I have attempted to check the user's settings of LaTeX Tools, and got nothing until now.
