After I run my process a number of times I keep getting this error. I am using a Write Range Workbook not using an Excel scope. I check task manager to see if Excel is running in background but it is not. The repeat cycle is long so there is plenty of time to release. I am doing this for my project so I want to use the “background” operation method before I do a workaround. I’ve had file issues before where I had to use a delay before reading a CSV after writing because it couldn’t find the file.
