Insisting "IndexError within GenericCSVData-loading

TraderOnes

Hello backtrader-experts,

half the day I spended in trying-searching-troubleshooting all docu-forum-google-entries...no change at all:
"IndexError" within dataloading is solid as a rock, does not change a bit...any advice?

CSV (GBPUSD, M5) has 100000 rows, for troubleshooting I have reduced to only 10
Original with dtformat = ('%Y.%m.%d %H:%M:%S'),

I have also changed to default-dtformat = ('%Y-%m-%d %H:%M:%S') with no difference

GenericCSVData is loading data with following parameters

import backtrader.feeds as btfeed
   dataLoad = btfeed.GenericCSVData(
        dataname = CSV_PATH + CSV_FILE,
        #separator = ",",
        #fromdate = datetime.datetime(2019, 1, 21),
        #fromdate = datetime.datetime(2020, 8, 8),
        #dtformat = ('%Y.%m.%d %H:%M:%S'),
        dtformat = ('%Y-%m-%d %H:%M:%S'),
        #dtformat = ('%YYYY.%mm.%dd %HH:%MM:%SS'),
        #tmformat=('%H:%M:%S'),
        datetime = 2,
        time = -1,
        timeframe = 5,
        compression = 1,
        open = 3,
        high = 4,
        low = 5,
        close = 6,
        volume = -1,
        openinterest = -1,
        nullvalue = 0.0,
        header = True)

Later

cerebro.adddata(dataLoad)

What ever I try/change/add/remove, it allways keeps: "IndexError: list index out of range".

with 10 rows only, you can see: CSV cannot be corrupt
"CSV_PATH + CSV_FILE" gives correct path to file, otherwise "No such file or director" would rise
I have tried both dtformats..therefore

...I am completely helpless, what can be the error.
Any advice?

Your data is backwards. Change the sort order so that oldest data points are first and newest are last.
