Can't find the folder

IHaveNoClue

Although my folder is in the correct path, the function can't find it.

I am new relatively new to programming, maybe some obvious mistakes?

import backtrader as bt

cerebro = bt.Cerebro()

data = bt.feeds.GenericCSVData(dataname='D:\Programme\Visual Studio Code\Projekte\D_Candles.csv', dtformat=2)

cerebro.adddata(data)

cerebro.run()

cerebro.plot()

All dependencies and packages were installed.

Error Message:

Traceback (most recent call last):
 line 9, in <module>
    cerebro.run()
  line 1127, in run
    runstrat = self.runstrategies(iterstrat)
  line 1210, in runstrategies
    data._start()
  line 203, in _start
    self.start()
  line 88, in start 
    super(GenericCSVData, self).start()
 line 674, in start
    self.f = io.open(self.p.dataname, 'r')
FileNotFoundError: [Errno 2] No such file or directory: 'D_Candles.csv'
PS D:\Programme\Visual Studio Code\Projekte>

What I tried so far:

just tiping the folder name
switching the backslashes
copied the folder in an other path
changed the folders name

I really appreciate your help.
Even if you know an alternative function I could try...
