Symbol 'XAUUSD t1' cached data not available or corrupted

Dear Spotware,

i hope you can help me / us with this problem.

I created a complete new and clean robot (just the template) with just one bool test parameter (to be able to start optimization), just to be sure that is has nothing to do with my other “real” bot.

I get the following output in the log during optimization:

01/08/2022 02:00:00.000 | Symbol 'XAUUSD t1' cached data not available or corrupted.
01/08/2022 02:00:00.000 | Symbol 'XAUUSD t1' cached data cleared.
01/08/2022 02:00:00.000 | Failed to get symbol 'XAUUSD': Symbol not found or has no quotes.

….

01/08/2022 02:00:00.000 | Symbol 'XAUUSD t1' cached data not available or corrupted.

01/08/2022 02:00:00.000 | Failed to get symbol 'XAUUSD': Symbol not found or has no quotes.

…. (error is repeating) …

I already deleted the backtesting cache completely.

The same problem also occurs for example with EURUSD, so also with other symbols.

And the same problem also occurs for example with t10, m1, m5 etc., so also with other timeframes.

It is the same problem like in the following threads:

cTrader Forum - cached data not available or corrupted

Thank you in advance for your help.
