@Christoph-Hart Yes fresh install of VS2022. Should I rollback?

I'm attempting to build HISE develop branch on Windows 10 with VS2022. However I get the following errors when attempting to build. Any idea where I'm going wrong? I followed the instructions exactly on the Github.

@d-healey

Reporting back this indeed solved my issue. Was able to compile a VST (had to turn off Use IPP in HISE settings as I could not find a download for it and it isn't mentioned anymore in the docs). But otherwise working great thank you so much!

@d-healey

I am not. I'll download and build/retry and report back.

You mentioned downgrading, any particular version to try out? I just don't wanna be going through installing 5+ versions if possible.

Attempting to export a VST FX on Mac with the following setup. My plugin thus far is a single HardcodedFX which is a converted RNBO patch and one knob on the UI linked to the HardcodedFX knob. My chain is otherwise empty. This is my first attempt at building a plugin so if I'm missing something please let me know I'm also happy to attach any addition stats about my setup.
