"Hot ice" planets such as this one are an all-too-common occurrence in ED and have had threads devoted to them before. And no, such a world cannot exist in the real-world universe, even when we consider the likelihood that "ice" doesn't just mean "water ice". A working planetological definition of "ice" is "any substance which would be a liquid or gas at standard Earth-normal temperature and pressure, but is solid at it's current temperature and pressure". Thus, water can become "ice"; so can ammonia, or nitrogen, or oxygen, or even hydrogen if it gets cold enough and/or the pressure gets high enough. But there is no substance in the universe that is gaseous at 1 atm and 288 K, but then becomes solid at higher temperatures and lower pressures. All substances become more volatile, not less, when you heat them and reduce the pressure - it's basic physics. Anything definable as "ice" ought to evaporate into gas at 592 K in a vacuum. This planet should be a giant comet, flash-sublimating all that ice out into a giant atmosphere until the pressure gets high enough to attain equilibrium.
Anomalies like this are a result of the Stellar Forge, and the way it determines the presence or absence of an atmosphere: a simple binary switch. Stellar Forge creates all the planets, then atmospheres on the created planets are simply switched "off" at random, regardless of whether the reported surface conditions physically allow a "no atmosphere" planet to exist. The probability of the switch being "off" is inversely proportional to it's mass - high-mass worlds are much less likely to have "no atmosphere".
Planets that actually have their atmospheres switched "on" are much more likely to obey the laws of physics. You can still get "hot ice" planets, but the "ice" is kept solid at such high temperatures under the pressure of thousands or millions of atms of pressure. For example, if we assumed that the OP's planet's "ice" was indeed pure water ice, then the laws of physics state that a surface of solid ice at 592 K is still physically possible - if and only if the planet has a surface atmospheric pressure of over 100,000 atmospheres. Such planets can also be found in ED.
