Question about job using powershell steps then SQL DTSX File - sql

Question

I have a simple SQL export to an XLS file. To keep the file clean, I have powershell steps:
Deletes the current file
Copies a template to the location
then runs a SQL step running a DTSX file that does a simple query and exports to the file.
when I run the DTSX file step it works fine, however after I run the two powershell steps it somehow permanently breaks the DTSX step, even if I run the job at that step only.
The only thing I can think of is I had to do set-location C: on the two powershell steps to have the code work, after i changed this the DTSX step constantly fails till I build it again, upload the new file, then it works until I run all three steps again. Any thoughts? I guess I could just build this in Visual Studio instead of using Powershell.
I tried to make the DTSX clear out the spreadsheet before it exports but that always failed, not sure if this is the way to go instead?
Step 1 (works every time):
Set-Location c:
Remove-Item -Path ""
Step 2 (works every time):
Set-Location c:
Copy-Item -Path "" -Destination ""
Step 3 (only works if I run it before ever trying the two above steps)
Type: SQL Server Integrations Service Package
Package Source: File system
I made it using a simple Export Data task.
Error after running the powershell steps, when running the DTSX step:
