QE in itself doesn't necessarily cause long-term problems. It's about what the state of the economy is when doing so. If you're on a job market recession, oversupply of goods and services, QE is a strategy that could correct the economy with little tradeoff.
Every economic strategy causes tradeoffs somewhere, it's about when, how long, why, etc that matter

QE causes problems in the long run. After a period of time, the state has to increase inflation again, simply to stay afloat.
