Chaos. Most governments have continuity plans so they shouldn't  fall apart, although in the short term figuring out the chain of command at all levels, everywhere, simultaneously will result in delays to any action. Any governments in precarious positions might see power grabs, coups, etc.

With modern supply chain management "just in time" practices the disappearance of half the workforce causes massive shortages. Thankfully, with half the population disappearing, there are plenty of supplies to raid from absent neighbors in the short term.

Those reliant on others for care; children, the elderly, those in assisted living, hospital patients, and so on probably experience issues, depending on how many caregivers vanish vs how many patients do.

Travel becomes difficult; planes are grounded until they know what caused the phenomenon, as are trains. The roads are cluttered with crashed cars from vanished people. Large cargo ships might needs crews sent out to them.
