This is the moment for Egypt to learn about backups. Dig a secondary canals next to the existing one. Under normal operations, have one serve the southbound traffic and the other one serving northbound traffic. In crisis, one can be blocked while the other switches direction every six hours or so. Yes, it is expensive. But not as expensive as having a canal blocked is for the world economy and the Egyptian government.
