This is the behavior in every version I tried, and I reviewed the FAQ for entries about Object.values.
In particular, this happens in version 4.3.5.

💻 Code

// Type
interface AxisInfo {
    config: { min: number, max: number }
}

// DOESN'T WORK: Case 1: Using interface
interface AxesInfo {
    x: AxisInfo
    y: AxisInfo
}

const axes: AxesInfo = {
    x: {
        config: { min: 0, max: 50 },
    },
    y: {
        config: { min: 0, max: 100 },
    },
}

// => config.max is of `any` type
Object.values(axes).forEach(({ config }) => alert(config.max))

// WORKS FINE: Case 2: Using union Record
type AxesInfo2 = Record<"x" | "y", AxisInfo>

const axes2: AxesInfo2 = {
    x: {
        config: { min: 0, max: 50 },
    },
    y: {
        config: { min: 0, max: 100 },
    },
}

// => config.max is of type `number`
Object.values(axes2).forEach(({ config }) => alert(config.max))

🙁 Actual behavior

Object.values(axes) is of type any[].
Object.values(axes2) is of type AxisInfo[], as expected.

🙂 Expected behavior

Object.values(axes) is of type AxisInfo[].

Note that this issue can be worked around with the rather cumbersome

export const values = <Obj>(obj: Obj): Obj[keyof Obj][] =>
    Object.values(obj)
