update powershell - script doesn't work anymore

Dear coll,

HELP ME!

I am a dummy powershell user; please, don't feed me with 10 line of code.

I have a simple script, replacing some text in a coda file; I made it with notepad++ 

It runs for years, but this week I updated to powershell7 and notepad++ 

and trouble started. 

If I run the script as usual (with powershell) I get a powershell popup, very briefly (some red text) and that's it. 

I checked all from every side, but I can not find any errors. 

Enclosed, I sent the first 3 lines of the script.

Get-ChildItem 'C:\Users\skidc\Downloads\CODA\*.*' -Recurse | ForEach {
(Get-Content $_ | ForEach { $_ -replace '00403278488', '00463026629' }) | 
Set-Content $_}
Get-ChildItem 'C:\Users\skidc\Downloads\CODA\*.*' -Recurse | ForEach {
(Get-Content $_ | ForEach { $_ -replace 'BE24733054476038                  GBP', 'BE24733054476038GBP               GBP' }) | 
Set-Content $_}
Get-ChildItem 'C:\Users\skidc\Downloads\CODA\*.*' -Recurse | ForEach {
(Get-Content $_ | ForEach { $_ -replace 'BE86731028224850                  GBP', 'BE86731028224850GBP               GBP' }) | 
Set-Content $_}
