I have read that reason 12 daw does not support vst 3.The reason rack included in reason 12 does but only when used with a different daw that supports vst3.
EZ drummer 3 is vst 3. I have also read that reason is working on implementing vst 3 with an unpromised timeline of Jan 2023.
Hope this helps a little.
