Additional context
I noticed that the parentheses are somehow URL-encoded. In other words, (・8・) became %28・8・%29.
I found the Stride.Core.AssemblyProcessor.dll in the directory C:\Users\ちーず(・8・)けーき\AppData\Local\Temp\Stride\AssemblyProcessor\netstandard2.0\BFE7D3C7730ED74698052516FFD23052551DA0B625689910B2D19CC3FA917F7C.

as a temporary "fix" you could create a windows VM with english as language and develop from there in stride

Another workaround would be to set your NUGET_PACKAGES environment variable to another safer path https://learn.microsoft.com/en-us/nuget/consume-packages/managing-the-global-packages-and-cache-folders

I found that MSBuild could be the one who escapes the braces in UsingTask.

@MineCake147E Thanks for the links.

I have attempted a fix in branch feature/unicode-path-fix but I didn't manage to reproduce the error locally, even when using a project name with parentheses.

Can you try to build Stride locally from that branch and see if that fixes it for you?

but I didn't manage to reproduce the error locally, even when using a project name with parentheses.

The key here is the user name set with parentheses included.
Otherwise, the TEMP in some *.targets files wouldn't contain any parentheses.

I suspect the one garbles the path could be UsingTask element. When I modified the AssemblyFile for some UsingTask that contains TEMP, using Unescape function, it worked as expected for me.
Though such workaround could end up introducing another problem.
