Warning on array to string

After an update to the latest version (around 15-Apr-24), there is a PHP Warning: Array to string conversion in “includes/acf-value-functions.php” on lines 96 and 122 which are:

96: if ( $store->has( "$post_id:$field_name" ) ) {

122: $store->set( "$post_id:$field_name", $value );

I tried to log the “$store” which is the following:

ACF_Data Object
(
    [cid] => acf-6
    [data] => Array
        (
            [8963:banner_image] => 
            [8963:banner_image:formatted] => 
            [9231:banner_image] => 
            [9231:banner_image:formatted] => 
            [9270:banner_image] => 
            [9270:banner_image:formatted] => 
            [14473:banner_image] => 
            [14473:banner_image:formatted] => 
            [9013:banner_image] => 
            [9013:banner_image:formatted] => 
            [14481:banner_image] => 
            [14481:banner_image:formatted] => 
            [9279:banner_image] => 
            [9279:banner_image:formatted] => 
            [15541:banner_image] => 
            [15541:banner_image:formatted] => 
            [1:banner_image] => 
            [22:banner_image] => 
        )

    [aliases] => Array
        (
        )

    [multisite] => 1
)

I have not changed the fields. Any ideas? Thank you.
