Problem with Plots using Julia V1.7.0 and VS Code

Using Julia version 1.6.4 and VS Code and running the following code

using Plots
x = 1:10; y = rand(10)
plot(x, y)
end 

I get the expected graph in the plot pane. However running the same code with Julia version 1.7.0 I get the following error code:

Error showing value of type Plots.Plot{Plots.GRBackend}:
ERROR: could not load library "libGR.dll"
The specified module could not be found.
Stacktrace:

changing the plot backend to

julia> pyplot()
Plots.PyPlotBackend()

results in the following warning message

How can I resolve this problem?

You could try build GR to re-install the GR backend

thank you for the very quick reply.
Stupid question: How can ich do this?

build GR

works. But what is about the pyplot backend?
