Error in powerapp code when replacing th existing sharepoint list with new list having same data

And sir, i am facing one more issue in same code:

If i am running my code, it is working properly.

But if i run same code ithrough deep linking, then it is not behaving same.

I have already enabled 'navigate in onstart' in seetings.

Below is picture-1, which is navigating to next equipment after saving response of one equipment. this is the screen which i got from running app normally.

But if i run the app through deep linking then on same page after filling response, i am not navigated to required next screen, instead it is navigated to Scrn_checklist

below is my code in app.onstart:

Set(var_Param,Param("AOA_Link"));

Set(Var_Eqp_Selected_1, LookUp(AOA_TPT_FT_startup_SK,AOA_Name=var_Param,Equipment_Name));
Set(Var_Rot_Selected, LookUp(AOA_TPT_FT_startup_SK,AOA_Name=var_Param,ROUTE));

If(Var_Rot_Selected = "OP Proc",

Set(Var_Befout_Count, First(Sort(Filter(AOA_TPT_outage_demo6_SK,field_1=Var_Eqp_Selected_1, field_2="Before Outage"),ID,Descending)).field_3);
Set(Var_Outage_Count, First(Sort(Filter(AOA_TPT_outage_demo6_SK,field_1=Var_Eqp_Selected_1, field_2="Outage"),ID,Descending)).field_3);
Set(Var_Befser_Count, First(Sort(Filter(AOA_TPT_outage_demo6_SK,field_1=Var_Eqp_Selected_1, field_2="Before Service"),ID, Descending)).field_3);
Set(Var_Service_Count, First(Sort(Filter(AOA_TPT_outage_demo6_SK,field_1=Var_Eqp_Selected_1, field_2="Service"),ID,Descending)).field_3);

Refresh(AOA_TPT_Outage_Process_Demo_Response_SK1);

If(Value(LookUp(AOA_TPT_Outage_Process_Demo_Response_SK1,And(Equip_Name=Var_Eqp_Selected_1, Response=Blank()),ID))=0,
ClearCollect(Clc_selected_equip_1,Filter(AOA_TPT_outage_demo6_SK, field_1=Var_Eqp_Selected_1));

ForAll(Clc_selected_equip_1,
Patch(AOA_TPT_Outage_Process_Demo_Response_SK1,Defaults(AOA_TPT_Outage_Process_Demo_Response_SK1),
{Equip_Name:field_1,
Outage_Step:field_2,
S_No:field_3,

);

ClearCollect(Clc_Befout_list,AddColumns(FirstN(Filter(Sort(AOA_TPT_Outage_Process_Demo_Response_SK1,ID,Descending), Equip_Name=Var_Eqp_Selected_1,Outage_Step="Before Outage"),Var_Befout_Count),"Temp_Status",

Navigate(Scrn_Outage_List_OP_Proc,ScreenTransition.Cover),

Set(Var_Rot_Selected_Cond,Var_Rot_Selected);

ClearCollect(Clc_Route_A_Equip_List,Filter(AOA_TP_FP_Integrated_Checklist_SK,ROUTE="Route A"));

Navigate(Scrn_CheckList,ScreenTransition.Cover)

);

And one more query, on running the app, app is showing me 'Scrn_Checklist' screen whereas i want to see 'Scrn_route list' screen on starting an app. Can you please help me to suggest where shall i change code to get required screen on starting the app.
