Unable to Reopen Workbench in Bronzeworks

Playing on PC using controller, defeated boss in Bronzeworks room inside Tempe of the Vaal and after crafting my weapon I opened the workbench to retrieve it, I accidentally hit the B button closing the menu. I cannot reopen the workbench to retrieve my weapon and do not know if it will be there when I next run the temple.

Room is Tier 1
