Check the github #issue https://github.com/dendronhq/dendron/issues/2214#issuecomment-1029025000 https://github.com/dendronhq/dendron/issues/2316 https://github.com/dendronhq/dendron/issues/2010 and found few people report the same issue. one of the workaround I found out was open the calendar view from workspace. once calendar is open, note preview is working and from terminal port I can see the running process start populate when I open workspace with calendar open.
