          I'm having the same problem.  It all appears after updating to julia 1.11.1:

You need to update Pluto to at least 0.20.3 to be able to use Julia 1.11.

Sometimes update Pluto does not update Pluto (like in your case) because of conflicting dependencies. Read https://plutojl.org/en/docs/update/ to learn more about why, and how to fix it.
