Immediate Window: The expression cannot be evaluated. A common cause of this error is attempting to pass a lambda into a delegate.

I can't find any workarounds. If someone can help me, I'll be very appreciated.

Steps to reproduce:

Create a Console Application, choose the .NET6.0.
Put the breakpoint in a Console.WriteLine, start the debugging.
When the debugger hits the breakpoint, put the following statement in the Immediate Window:

new[]{1,2,3}.Select(x => new{Index = x})

Select this statement, and execute any of the Dump As ... commands.

Expected result: Object is dumped successfully.
Actual result: Exception: The expression cannot be evaluated. A common cause of this error is attempting to pass a lambda into a delegate.

Notes:
There is a workaround for new[]{1,2,3}.Select(x => x) - just add ToArray() call at the end of the statement:
new[]{1,2,3}.Select(x => x).ToArray()
Also, replacing the anonymous type with a ValueTuple and ToArray runs without errors:
new[]{1,2,3}.Select((i, x) => (i,x)).ToArray()
