Workspace = renderer crash

insider0.13.10, Mojave10.14.6, upon starting new 0.13.10, with new Preview enabled, Obs freezes at workspace—letting it stay that way eventually results in renderer crashing; no change from deleting either or both old workspace files, or from deleting Workspaces-Plus plugin; only relief was from removing entire plugins folder…(is that from enabling the new Preview, or from the switch to the v.6 rendering engine, or both?)

looks like it’s plugin problem if removing all plugins fixed it.
