Hello,
Apologies for long response time but we tried to investigate this problem in many cases and we realized this is not a problem with plugin but with engine itself. Third-Party plugins (not only our plugins) placed in the engine folder (including downloaded from Marketplace) don’t include arm64 binaries. If you want to make it working for arm64, please simply move installed plugins from [ENGINE_FOLDER]/Plugins/Marketplace to [PROJECT_FOLDER]/Plugins.
Thank you for your patience.
