This is really easy to replicate
using PackageCompiler
create_sysimage(:DataFrames, replace_default=true)
``
then restart Julia in VSCode
using DataFrames
a = DataFrame(a=1:3)
vscodedisplay(a)
Then you will see that `vscodedisplay` no longer works
julia> vscodedisplay(a)
┌ Warning: Cannot display values of type DataFrame in VS Code.

Should I file an issue with vscode plugin or PackageCompiler.jl? Feels like the former
