Unstable Code Folding Function in VSCode

Type: Bug

The code folding feature in Visual Studio Code is experiencing issues. Sometimes, code blocks cannot be folded or unfolded, requiring a restart of VSCode to resolve the issue. Additionally, display issues occasionally occur.

When editing code, attempts to fold code blocks are unresponsive.
Already folded code blocks cannot be unfolded.
The issue temporarily resolves after restarting VSCode but reoccurs after a while.
Display issues sometimes occur, such as misaligned code lines or partial code disappearance.
