Multidimensional Array Laravel

I'm new to laravel and I'm trying to loop through this multidimensional array in the view of blade template but unable to get the elements. I tried using nested foreach but that doesn't work. I'm unsure what else to do. Please help

Array
(
[2] => Illuminate\Support\Collection Object
    (
        [items:protected] => Array
            (
            )

    )

[3] => Illuminate\Support\Collection Object
    (
        [items:protected] => Array
            (
                [0] => stdClass Object
                    (
                        [ActivityID] => 1
                        [WaiverID] => 3
                        [ProgramID] => 1
                        [ActivityName] => Waiver3 Activity 1
                        [WaiverName] => Waiver 3
                        [ID] => 3
                        [WaiverDescription] => 
                        [ProgramID] => 1
                    )

                [1] => stdClass Object
                    (
                        [ActivityID] => 2
                        [WaiverID] => 3
                        [ProgramID] => 1
                        [ActivityName] => Waiver3 Activity 2
                        [WaiverName] => Waiver 3
                        [ID] => 3
                        [WaiverDescription] => 
                        [ProgramID] => 1
                    )

                [2] => stdClass Object
                    (
                        [ActivityID] => 3
                        [WaiverID] => 3
                        [ProgramID] => 1
                        [ActivityName] => Waiver3 Activity 3
                        [WaiverName] => Waiver 3
                        [ID] => 3
                        [WaiverDescription] => 
                        [ProgramID] => 1
                    )

            )

    )

)

When I do a foreach like this

@foreach ($waiverActivityforTable as$waiverActivityforTableValue)           
    
@endforeach

I get:

[] [] [{"ActivityID":1,"WaiverID":3,"PHAProgramID":1,"ActivityName":"Waiver3 
Activity 1","HCVWaiverName":"Waiver 
3","ID":3,"HCVWaiverDescription":null,"phaProgramID":1},
{"ActivityID":2,"WaiverID":3,"PHAProgramID":1,"ActivityName":"Waiver3 
Activity 2","HCVWaiverName":"Waiver 
3","ID":3,"HCVWaiverDescription":null,"phaProgramID":1},
{"ActivityID":3,"WaiverID":3,"PHAProgramID":1,"ActivityName":"Waiver3 
Activity 3","HCVWaiverName":"Waiver 
3","ID":3,"HCVWaiverDescription":null,"phaProgramID":1}] 

Tired nested foreach: I tried:

    @foreach ($waiverActivityforTable as $waiverActivityforTableValue)
        @foreach ($waiverActivityforTableValue as $test)
            
        @endforeach
    @endforeach

but I get an error: htmlspecialchars() expects parameter 1 to be string, object given
