HI,

I just upgrade to 1.10.2 and hit crash which is more like VSCode tools crash when I run nd debug my old code. To rule out my code error, I just create a simple test.jl like below

```julia
println("This is test1")
println("This is test2")
println("This is test3")

```

- If I run this code in VSCode, or run in Julia REPL, it can run and output correctly.
- If I set breakpoint at the first line, run debug in VSCode, when it break there, and click “continue” , it can run correctly.
- If I set breakpoint at he first line, when it break there, and click “step over”, it has below crash

```julia
This is test1
┌ Error: Some Julia code in the VS Code extension crashed

```

Then I tried to modify as below with function, it can step run but has the same crash when return from function.

```julia
function test()
    println("This is test1")
    println("This is test2")
    println("This is test3")
end
test()

```

I degrade to 1.10.1. Then everything is OK.

my environment:  
MacBook Pro M1 Pro,  
OS Sonama 14.4  
VSCode: 1.87.1  
Julia extension: v1.75.2

Thanks.

I’m getting the same with  
Ubuntu 22.04.3 LTS  
VSCode 1.87.2  
Julia Extension 1.75.2

[Debugger crashes with AssertionError: !(is\_generated(method)) · Issue #3558 · julia-vscode/julia-vscode · GitHub](https://github.com/julia-vscode/julia-vscode/issues/3558) mentions the same exception in the comments but it looks like a separate issue. I’ll ask there if they want it logged seperately.

Same here with:  
Ubuntu 22.04.4 LTS  
Julia 1.10.2  
VSCode 1.87.2  
julia-vscode 1.75.2

The same fix reported by @chaojin (degrading to Julia 1.10.1) worked for me.

Just test with Julia 1.10.3 and julia-vscode 1.76.2, this crash has been solved.
