While Conifold is basically correct, Marx did generalize to a certain extent about crises. The dominant class will enter a crisis when the current norms, laws, and ideologies that sustain it place unbearable constraints on technical advances in the mode of production.
This is most evident in the Capitalist phase and the bourgeois revolutions, but is presumably a dialectical conundrum in any age. The laws that sustain the given order and class domination will come to seem more and more "irrational" and intolerable as the improved forces of production advance beyond them. The internal contradictions accumulate to the point of implosion.
This is not, I should add, the sort of technical determinism or "science of history" favored by Engels and, more crudely, the orthodox Bolsheviks. It would take the form, in any given historical moment, of highly complex, unpredictable stresses in the social order, involving conscious reactions, politics, and culture every bit as much as new machines and material overproduction.
Crises like the pandemic or protests simply do not rise to this level, though they could catalyze other forces, who knows? A better example of what Marx suggests would be the stresses on "national" legal-political structures and institutions caused by the computerization and globalization of Capital. Capital can extend the division of labor across national borders, yet still relies on a fiat currency secured by national debt and taxation.
Another would be the inherent contradiction between the advances of commodified digital information and the outmoded laws of ownership, patents, copyright, etc. based on 18th century bourgeois rights to "property," in the form of land or natural resources. Napster, probably more than BLM or Covid-19, presented a true dialectical crisis for the bourgeois that is still playing out. Merely human crises are just market opportunities.
