Found plugins with same names and architectures, Assets/Extensions/ParadoxNotion/SLATE Cinematic Sequencer/Utility/UTJ/Plugins/x86_64/AlembicImporter.dll () and Assets/Extensions/ParadoxNotion/SLATE Cinematic Sequencer/Utility/UTJ/Plugins/x86/AlembicImporter.dll (). Assign different architectures or delete the duplicate.
Maybe default Import Settings for AlembicImporter aren’t optimal?
Until I find a proper solution for this, please delete the Folder “x86_64” under Plugins folder and then you will be able to build correctly.
Let me know if this works for you.
Thanks and sorry for the trouble.
