Project builds may fail on a non-English version of Windows. The error occurs if the path to the linker file includes non-ASCII characters. The allowed characters are: A-z, 0-9, '-' (dash), _(underscore), '/' (slash), '.' (period).
Open the project properties and go to the page. In the Script files (-T) field, ensure that the path to the linker file uses the allowed characters and that all included variables are resolved to ASCII strings:

If necessary, relocate the linker file to a folder whose path includes the allowed characters, or rename the folders properly.
If the issue is caused by a variable, consider using the relative path that excludes the use of the variable. For example, the Script files (-T) field contains the following path:
${ProjDirPath}/Project_Settings/Linker_Files/<project_name>.ld
If the ${ProjDirPath} variable holds the string with invalid characters, replace the value in the Script files (-T) field with the relative path that does not use the ${ProjDirPath} variable:
../Project_Settings/Linker_Files/<project_name>.ld
The update takes effect after you click Apply.
If the errors still occur, go to the page and replace "${ProjDirPath}/include" with "../include".
