"Not enough information to infer type variable T" android studio error

I'm following a series of kotlin based tutorials on youtube for android studio jetpack compose, but now android studio is giving me the error "Not enough information to infer type variable T" for keyframes, while everything is exactly copied from the tutorial video, what am i doing wrong?

Code (Text):

1. class MainActivity : ComponentActivity() {
2.     override fun onCreate(savedInstanceState: Bundle?) {
3.         super.onCreate(savedInstanceState)
4.         setContent {
5.             var sizeState by remember { mutableStateOf(200.dp) }
6.             val size by animateDpAsState(
7.                 targetValue = sizeState,
8.                 keyframes {
9.                     durationMillis = 5000
10.                     sizeState at 0 with LinearEasing
11.                     sizeState * 1.5f at 1000
12.                     sizeState * 2f at 5000
13.                 }
14.  
15.             Box(modifier = Modifier
16.                 .size(size)
17.                 .background(Color.Red),
18.             contentAlignment = Alignment.Center) {
19.                 Button(onClick = {
20.                     sizeState += 50.dp
21.                 }) {
22.                     Text("Increase Size")
23.                 }
24.             }
25.  
26.         }
27.     }
28. }
