My onOpen trigger is running only half of the script - google-apps-script

Question

My script onOpen is running only half of the script. When I try to run the scrip manually it works, but when I refresh the spreadsheet, it only changes the number to 5 in cell A10.
function onOpen() {
const ss = SpreadsheetApp.getActive();
const rok = ss.getSheetByName('ROK');
const id = ss.getSheetByName('ID');
const kontrola = rok.getRange('I4').getValue();
ss.getSheetByName('DATA').getRange('A10').setValue(5)
if (kontrola == 1) {
//iGV synergie copy
const term = rok.getRange('G3').getValue();
const name = ('iGV'+term);
const Synergie = id.getRange('C5').getValue();
const iGVSarchiveid = id.getRange('C3').getValue();
const iGVSarchive = DriveApp.getFolderById(iGVSarchiveid);
const iGVS = DriveApp.getFolderById(Synergie).getFilesByName('iGVxF&L');
const copyiGVS = iGVS.next().makeCopy(name);
const urlcopyiGVS = copyiGVS.getUrl();
DriveApp.getFilesByName(name).next().moveTo(iGVSarchive);
ss.getSheetByName('DATA').getRange('J3').setValue(urlcopyiGVS)
}
}

Issue:
The issue is that you are using a simple onOpen trigger which according to the official documentation has the following restriction which is relevant to your case:
Simple triggers cannot access services that require authorization. For
example, a simple trigger cannot send an email because the Gmail
service requires authorization, but a simple trigger can translate a
phrase with the Language service, which is anonymous.
Essentially the simple trigger can not access DriveApp because it requires authorization to do so.
Solution:
Create an installable onOpen trigger instead. Rename your function and use any name except for onOpen and then go to your current project's triggers and create an installable trigger for your function (in my example myFunction):
function myFunction() {
// code goes here
}
