My exact error message in MetaTrader is the same. One person thinks this issue is related to the new version of MetaTrader4. I uninstalled the new version of MetaTrader4 and installed the older version, but the issue was not resolved. Another friend suggested that I upgrade from Windows10 to11. Do you think there is another solution to this problem?

When I perform a backtest in MT4 using a robot created with fxdreema, it gives error138 and does not open any trades. However, when I backtest the default robots in MT4, there are no errors. What could be the reason for this? Additionally, I have uninstalled and reinstalled MetaTrader, but the error persists! If anyone knows the cause, please help me. Thank you
