Help me please, I have this problem when I try to perform an atomospheric correction

This was reported several times when the path to the data contains spaces or special characters (e.g. ü, ø,…, here: Problems with atmospheric corection (L1C to L2A))

Could it be that you renamed the folder which contains the image data?

Try placing the data in a simple folder, like
c:\temp\S2B_MSIL1C_20190402T102029_N0207_R065_T32TMT_20190402T130831.SAFE
