I rely very heavily on the iOS Shortcuts app (formerly known as Workflows). So when the Shortcuts app would crash every time I tried to open it the last couple of days it was beyond frustrating. So I did some searching and found the answer and it turned out to be an incredibly easy fix. Rather than repeat everything here I will just point you to the source. The problem turned out to be a “bug” with how the Shortcuts app was syncing shortcuts with iCloud. Turning off the Shortcuts iCloud syncing and turning it back on again fixed the problem.
