Have you tried FideDAC Mapping? From the link provided by Dmitry I see two things you can try (specify type name in column alias and mapping):

It's better to avoid antifreeze and do the transfer in a separate thread using TTask for example.

https://docwiki.embarcadero.com/RADStudio/Athens/en/Supported_Target_Platforms Maybe 12.0 supported Android 8.1 but 12.2 not. And if you filter the log only for your app at the and in the last page(s) should be some clues for why app closes.

I suppose you know that Android 9 is not supported by Delphi 12. A log or a message of the error would help to have a better response.

That means that TLocalDefault.GetStringValue returns expected string? Result in GetStringValue is what you expect?

EurekaLog can send data to a bug tracker. See https://www.eurekalog.com/help/eurekalog/index.php?bug_trackers_setup.php We use MadExcept and data are sent to Mantis that uses MySQL (actually MariaDB). An SQL server can handle a huge amount of data.

I think this should be reported. Something like this I discovered in FastReport and it surfaced in rare circumstances. First when I reported it was ignored till I come with a case to reproduce. Because this, the report should have also the link to documentation.

tqdm is a text output "progress bar" for a console app. And you want to show this text output along a graphic ProgressBar from FMX? Probably in something like TMemo component?

You installed 12.2 Patch 1 that is binary compatible with 12.1 but not with 12.2. If you installed some components compiled for 12.2 then it is understandable that your 12.2 Patch 1 IDE is unstable. Can this be the case or you are sure all your third-party components are compatible with 12.2 Patch 1 and 12.1?

But then it should setup Python engine to run in other thread context. I don't think it is worth.

PythonEngine appears to be nil. Did you checked there if Self is nil?

I am not sure right now but I suppose ServiceCreate and ServiceExecute are not in the same thread. Why not creating PythonEngine in ServiceExecute?

The protocol doesn't change suddenly. You need to install a new MySQL version for that to happen. In this case you need to check that the library you use for connection supports that version: https://docwiki.embarcadero.com/Status/en/FireDAC_Database_Support Same for MyDAC: https://www.devart.com/mydac/compatibility.html

As a side note. unit Vcl.Edge; .... initialization FSetExceptMask(femALLEXCEPT); SHDocVw, Vcl.Edge and other units set the mask. If someone is using TWebWrowser for example all exceptions are masked but not on all machines is so and I do not have time now to investigate why.
