Pycharm Remote Debug local file, path mapping error. Pycharm 2020.2.3

Hi,

I'm using pycharm debug server to debug local files for some reason, so I just set path mapping to the same(actually, leave them to null does the same).

For example, 

And when I start to debug, the local path, in this case, "D:/projects/test1", will change into "d%3A%5Cprojects%5ctest1", so it can't find the local file(although they are the same file).

So, how can I solve this?

Thank you.
