Bit Form critical bug

Bit Form sends me to a blank screen when I try to connect it directly to Trello or Zoho Bigin and gets all its menus frozen in the left WordPress bar.

When I try to connect a Bit Form contact form to the same apps (Trello / Zoho Bigin) through Bit Integrations, the same thing happens when I choose this apps as actions. It sends me to a blank page and the Bit Integrations menus in the left WordPress bar are frozen.
