Hi
Thijs,We
could replicate the reported scenario when using CollapseAll method in the
Loaded event of the SfListView. We will analyze the reported scenario at our
source level and update you with further details on May 5, 2022. We appreciate
your patience until then.Meanwhile,
we suggest you set the DataSource.AutoExpandGroups
to false to collapse all the groups on loading. Please refer to the
following code snippets for more reference,

protected override void OnAttachedTo(SfListView bindable)
  {
      ListView = bindable;
      ListView.DataSource.AutoExpandGroups
  = false;
     
  ListView.DataSource.GroupDescriptors.Add(new
  GroupDescriptor()
      {
          PropertyName = "ContactName",
          KeySelector = (object obj1)
  =>
          {
              var item
  = (obj1 as ListViewContactInfo);
              return
  item.ContactName[0].ToString();
          },
      });
      base.OnAttachedTo(bindable);
  }
