It must be the UI thread in Winforms
Correct. Your async method tries to return to the current "execution context" after the await. In a WinForms app, when the async method was called from the UI thread, it tries to return to the UI thread. But you've blocked the UI thread by trying to execute the async method synchronously:
this.GetAccessToken().GetAwaiter().GetResult(); // Blocks the UI thread
Therefore, the async method can never complete.

If you're not accessing the UI from your GetAccessToken method, you can add .ConfigureAwait(false) to your ExecuteAsync call, so that the rest of the method can complete on a thread-pool thread:
this.Result = await this.App.AcquireTokenForClient(this.ResourceIds).ExecuteAsync().ConfigureAwait(false);
Otherwise, you'll need to find a way to avoid blocking the UI thread. You'd need to make the calling method async. However, you want to avoid async void methods[^]. A simple solution is to move the code into a task-returning async method, and assign the returned task to a "discard" variable to avoid the compiler warning.

Old code, don't use:
private void ButtonClick(object sender, EventArgs e)
{
    // Some code...
    this.GetAccessToken().GetAwaiter().GetResult();
    // Some more code...
}
Bad fix, don't use:
private async void ButtonClick(object sender, EventArgs e)
{
    // Some code...
    await this.GetAccessToken();
    // Some more code
}
Better fix:
private void ButtonClick(object sender, EventArgs e)
{
    _ = SomeMethodAsync();
}

private async Task SomeMethodAsync()
{
    // Some code...
    await this.GetAccessToken();
    // Some more code
}
