Recently I suddenly couldn’t find the input cursor in the cell of the Jupyter notebook, so I couldn’t type or edit any code. Kernels looked fine, because I could create and rename ipynb files, or run previous code. The Header and Toolbar also work, but all shortcuts are disabled and metadata cannot be edited. The running consle in edge is shown below. What exactly is the problem?
Happened to me as well in Opera. After I disabled all the extensions, it worked. So the issue must be in the browser.
