Breakpoints not working

[RecursivePineapple]

When I set a breakpoint in code that I know is running, it never breaks. Previously, I could revert to 0.58.0 to fix this, but it seems that every version (including the prereleases) are broken now. I removed every vscode file I could find in case this was caused by an invalid cache, but it hasn't fixed it. I can pause threads manually, it's just breakpoints that don't work. I don't see any errors in the logs.

System java version: 21 (though I also tried with JAVA_HOME set to 17)
Debuggee java version: 21
Debugger java version: 1.8.0_442 (there's a warning about it)

I'm not sure what else I can check, any advice is welcome.
