Hi, I’m a quite new Julia user. I’m currently trying to implement a simple gas model using [Agents.jl](https://juliadynamics.github.io/Agents.jl/stable/). To do this, I’ve been following a couple of tutorials from the docs, namely Continouos Covid19 and Flocking. To show the results, both examples call the `abm_video` function, in conjuction with calling `using InteractiveDynamics` and `using CairoMakie`. The problem is that when I try to do so, I get the error from the title:
> ERROR: No backend available (GLMakie, CairoMakie, WGLMakie)!
> Maybe you imported GLMakie but it didn’t build correctly.
> In that case, try `]build GLMakie` and watch out for any warnings.
> If that’s not the case, make sure to explicitely import any of the mentioned backends.

I’ve tried `]build CairoMakie`, but it didn’t help. I’ve also tried using the GLMakie backend but I get the same error. When calling `] status` all packages are present. And all packages have been recently installed with `] add`, so they should be the updated to the last available version. I’m on Windows 10, by the way. One thing to note is that in Pluto this works fine: calling `abm_video` correctly saves the file to disk. The error happens when using the Julia REPL directly. I’ve also noticed that both GLMakie and CairoMakie get precompiled when calling `using GLMakie` or `using CairoMakie`, not sure if it’s something useful to know or not.
What can I do to solve the issue?

I could try to troubleshoot this if you could figure out a minimum working example that produces this error, and if you could include your current `project.toml` file!
