After Effects on Windows on ARM64 doesn't load my plugin

My custom file exporter plugin works great on After Effects on Windows on x86_64. But recently Microsoft asked if I’m interested in supporting ARM64, so I started working on this.

Both Premiere and After Effects plugins work perfectly on x86_64. The Premiere Pro plugin works also perfectly on ARM64, but the After Effects plugin doesn’t work.

We investigated together (using Procmon and TTD) but only found this in the registry:

HKCU\Software\Adobe\After Effects\26.0\PluginCache\en_US\VoukoderPro.aex_74697f7d-6eaa-731e-5ba9-290933586ec3\Ignore = 1

Do you know why and how this could happen? How and where can I find more information to solve this issue?
