[fp4code]

Thank you for reporting an issue about Pluto! Let's get it fixed!

To report an issue, you need two things:

1. 📹 A video recording demonstrating the problem:

2. 📝 A short Pluto notebook file

3. 🤕 Try to clearly explain what the problem is, it might not be obvious to others!

In a Pluto notebook, the "use Reduce" command never ends. I have to stop it and restart it.

Same thing with julia-1.6 1.7 1.8 master Same thing with Chromium, Firefox

The CPU is consuming time in Chrome, not in Julia.

Please call "using Reduce" in a REPL before, to make sure that Reduce is built. Or observe that Julia stops working before trying to stop the "using Reduce" cell.

The problem may be on the Reduce side, but I think the Pluto specialists can identify the source of the bug.
