VSCode - debugger crashes when I am using TestItems

General Usage

Using Julia debugger in VSCode is generally buggy (as other posts attest), but I have not seen this problem reported yet:

If I am using TestItems (see below) then it’s impossible to debug - The debugger crashes on start:

This is reproducible with this test:

using TestItems

@testitem “simple fill test” begin
@test 1 == 1
