Recover Missing Block

We experienced some issues with our timeline with UNA 13.1, we are now on Timeline 13.0.13. When we experienced these issues I deleted the Block. "Profile Feed (Timeline) from "Pages > Persons > View Profile"

The block is now missing from the "ADD BLOCKS" menu under "Timeline"

I have tried to add it back, but each time I save it the block disappears and is not available.

@LeonidS I can not select "System->Service block" as there is no block called Service block

@Alex T⚜️ added here as requested.

Studio->Developer->Pages->Persons->View profile->Add block area. In the appeared menu choose the System->Service block and save it. Then edit it as thr Module=Timeline (instead of Persons) and add to the Conent field the following code:

array (

 'module' => 'bx_timeline',

 'method' => 'get_block_view_profile',

 'params' => 

 array (

  0 => '{type}',

 ),

)

The second I change the block to the parameters listed below it disappears completely.
