VST3 Plugin not readable

[MicheleBonventre]

Extremely now, i'm compiling on Visual Studio 2026 (release)

Plugin works in HISE, when i export and load the .vst3 on Live or Cubase it says not readable.
I'm completely at a loss and i have a deadline in 3 days.
What could be the issue?

@MicheleBonventre What's the deadline for?

Does it work in Reaper?

Does a minimal test plugin work?

The deadline is for an exam, but it's really a basic compressor.

I did not test it in reaper because i don''t have it.

I built it by following your series on YT (You are a savior) and it works perfectly while inside the HISE framework. I exported it following your guide but it doesnt seem to work.

You are exporting as an effect?

Does a minimal test project work?

Are you using faust/scriptnode?
