os.path.exists returns False on Windows although file exists (MAX_PATH 260 Windows API problem?)

I am getting a false negative on a file that exists with os.path.exists.

path = '\\\\fgcz-biobeamer.uzh.ch\\Data2San\\p3061\\Proteomics\\TIMSTOF_1\\spfammatter_20200317\\3-17-2020_22-17-14_200ngHeLa_stdPASEF_100minGT__MSdataReduction_moderate_Rep1_520_1_Slot1-46.d\\stdPASEF_100minGT_MSdataReduction_moderate_520.m\\microTOFQImpacTemAcquisition.method'

os.path.exists(path) # returns false

len(path) # returns 260

I did some googling and what I found is:

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.

(https://docs.microsoft.com/en-us/windows/win32/fileio/naming-a-file)

Is there a different python API that can handle paths of that length I could use?

Some windows tools can't handle those paths (although I did create this file using robocopy which is a windows tool).
