Problems with new projects (Inaccesible due to its protection level) [SOLVED]

First of all sorry for my english, is not my main languaje.
Every project i create starts with 25 errors that i cant fix. All problems say that something (i mean that 25 diferent things are unaccesible) is inaccesible due to its prtection level. I installed 2 versions of the 6.1 and the projects create broken. A friend with the same version doesnt have those problems

I know nothing about Unity Collaboration but it looks to me like you don’t have it setup correctly. Are you trying to collaborate with your friend?

see if this helps:

I’m afraid the reports of new projects failing to compile packages are common recently. It’s not Unity version specific, and all things point to system issues at this point - permissions, antivirus, system settings/policies, and so forth.

Usually those package errors only occur when the installed packages specific versions are not tested together or not compatible with the editor version, but this isn’t something that’s normally occuring in new projects.

Try creating the project under the user’s Documents folder to rule out permissions, and with Antivirus disabled to rule out interference from AV (project folders should always be excluded from live/online scans for performance reasons alone).

Since 6.1 is a tech release without further updates, same as 6.2, check if 6.0 or 6.3 works for you.

I tried what you said because the project was in an HDD that i use only for files but nothing worked except changing the version to 6.0.
Thanks for the help

I didnt even know that unity collaboration exists xD
Tnx for the help and the time

I dont know if there is a way to mark this problem as solved

You can click the checkmark icon on the post with the solution:

If you have an SSD, that’s where you should place Unity projects. HDDs are terribly slow. If you don’t have an SSD, get one, and be blown away (especially if you install Windows to it - booting from an SSD vs HDD is like day and night, seconds to minutes, chocolate to spinach/broccoli/brussels sprouts/asparagus).

I have the same problem, in a new unity 6.0 project without doing anything I am getting 25 different errors, all of them are either

‘SettingsWindow’ is inaccessible due to its protection level
‘SplitterState’ is inaccessible due to its protection level

Same problem with SettingsWindow and SplitterState in 6.3

I updated all the Unity assets that needed updating and relaunched with 6.3 and errors were resolved
