• The cursor changed from | to  ▌ Solution

▌: The cursor has entered the rewrite state, while the opposite is the insert state.
In the insert state, it means that new content can be inserted in front of the cursor positioning point, and the subsequent content will not be replaced. If you enter the rewrite state and enter new content at the cursor positioning point, the content at the cursor positioning point will be replaced.

Solution : Use the insert key on the keyboard   to switch states
