After i updated unity i got these errors. how do i fix it. i have no idea what it is talking about
Those are Warnings. Errors would be red.
Do you use Visual Scripting, along with Version Control?
i am using bolt. but the project is very new so i have not opened a single script yet
See if you have Version Control installed by going into Window > Package Manager. If you have, then your warnings are likely related to this issue.
If you are a Bolt user, updating/building Unit Options may help with resolving some issues related to warnings.
