Thank you David for your reply!

Yes I found the bug of reading then converting the string to DateTime in the code already.

The project information:

 - Delphi 10.4.3

 - Target: 32-bit release

 - Omni Thread version 3.07.9

 - Windows 11 Home 64-bit

When executing in debug mode (F9), the Omni thread raises the exception:

When breaking, it lands to OtlTaskControl:

It should be mentioned that the project executes normally (no exception)

in mode without debug (Ctrl+Shift+F9).

Thank you in advance for any idea.

Thank you very much to Hans, David and Fr0sT. I really appreciate your valuable advices.

Please kindly advise when we use this component over the other and vice versa
