The "Run to cursor" button was removed in R2021b.
Starting in R2021b, a Continue to Here button shows up to the left of the code folding margin when you are stopped at a breakpoint in a script, function, or class file:
In addition to the button, there is also a context menu item when right-clicking on a line number in the margin which should also be available under the same circumstances:
There is also a new Run to Here feature that will allow you to run the code to a specific line and pause in scripts, even when not in debugging mode:
Again, there is a corresponding context menu item when right-clicking on a line number in the margin:
Note that "Run to Here" is only available in scripts, not in function/class files.
