Hello @MD. ALAMIN HOSSEN, 

Welcome to Microsoft Q&A forum.

From the first screenshot, I can see that the error said: Path: … exceeds the OS max path limit. The fully qualified file name must be less than 260 characters. The OS(Windows OS) does have this well-known restriction. See this document: Maximum Path Length Limitation.

In the Windows API (with some exceptions discussed in the following paragraphs), the maximum length for a path is MAX_PATH, which is defined as 260 characters. A local path is structured in the following order: drive letter, colon, backslash, name components separated by backslashes, and a terminating null character. For example, the maximum path on drive D is "D:\some 256-character path string<NUL>" where "<NUL>" represents the invisible terminating null character for the current system codepage. (The characters < > are used here for visual clarity and cannot be part of a valid path string.)

If I want to change the folder of the project what can I do so this error does not happen?

As it’s the OS restriction, the solution is moving your solution to another directory which is closer to the root.

Best Regards,

Tianyu
