You are never 100% safe. You could be killed by a car, a falling plane or a meteorite an hour from now. Or an artillery shell or nuke just after the start of an unexpected war. Or that painful spot that you have could turn out to be terminal cancer, which could kill you within 3 months.
Also any currency and any set of stocks can go to near-zero faster than most imagine. A natural disaster can happen that simultaneously wipes out your house (if you have one) and your insurance company. (This is actually the reason I'm insuring my house with the same company that holds my mortgage, so at least I don't have to pay the mortgage if they're wiped out in such an event.)
The real question is how much risk are you willing to accept, and what costs are you willing to pay to mitigate the risks. And of the above, I think the main risk driver was to go abroad (paired with being unlucky about covid's timing).
Going abroad while depending on a domestic bank with a log-in method that would soon expire was adding to the risk.
The combination of the above put you into a small subset of the population, meaning you and people like you didn't have leverage when the disaster struck.
But you _were_ unlucky. And if luck is bad enough, you're never completely safe.
