Goland sqlite database is locked (5) (SQLITE_BUSY) Error/Warning - windows

Question

The following simplified code just go over a sample table and update it row by row (assume this update can not be done by an SQL query, and it might be on some of the rows only). However when using the sqlite driver, it fails on the update with the "database locked warning".
I am running on windows with the go sqlite driver. This error does not happen with PostgreSQL database.
import (
"fmt"

type Tbl struct {
ID uint `gorm:"primaryKey,autoIncrement"`
Name string
Code int
}
var dbConn *gorm.DB
func main() {
db, err := gorm.Open(sqlite.Open("sqlite.db"), &gorm.Config{})
if err != nil {
log.Fatal(err)
}
err = db.AutoMigrate(&Tbl{})
if err != nil {
log.Fatal(err)
}
// clear the table and add sample data
db.Exec(`delete from tbls where 1=1`)
tblsclice := make([]Tbl, 50)
for i, _ := range tblsclice {
tblsclice[i].Name = fmt.Sprintf("This is line %d", i)
tblsclice[i].Code = i * 10
}
db.Create(&tblsclice)
// update each line (assume that it can not be updated by sql- this is just a sample)
rows, err := db.Model(&Tbl{}).Rows()
if err != nil {
log.Fatal("Error scanning DB rows", err)
}
defer rows.Close()
var t Tbl
for rows.Next() {
// ScanRows is a method of `gorm.DB`, it can be used to scan a row into a struct
err := db.ScanRows(rows, &t)
if err != nil {
log.Fatal("Error scanning DB rows", err)
}
t.Name = " NAME " + t.Name
//---- this throws the warning-----: database is locked (5) (SQLITE_BUSY)
db.Save(&t)
}
