I do have some company managed antivirus installed. It never impacted package installs before luckily, I just deleted the node_modules folder again and this time instead of clicking ‘Install Preview Server’ before clicking ‘Start Preview Server’, I just clicked ‘Start Preview Server’ which seems to run the npm install then keeps the terminal open after and starts Vite and it runs fine now. I’ll keep an eye on the issue as it has happened a few times on different blend files to see if this process is the fix.
