I've found 922325356 so far. Finding anything > 929e6 is going to be really hard, at least using my dumb method.

Kudos! I don't think there is a smart method.

Is there a solution, or are we trying to blindly find a solution?

You really do not have to worry so much, because there are many solutions. If no solutions had been known before the task was published, the "loophole" barrier would have been set lower.

Somehow, all of us have failed so far to find one of those "many solutions" :(

After running overnight I've found several above the barrier now. Best was a lucky find at 924286698.

Now I have found a matrix which is no Latin Matrix (same digits in the same line) and has a determinant 924844032, and each digit appears 9 times.

If there is a Latin Matrix with the same determinant - I don‘t know.

Update: 928284672
Unfortunately my code has a bug, which I try to find, but I have checked my results externally before presenting them here and sending them to the puzzlemaster.

I believe you (general you) are misinterpreting the puzzle. Sure, the plain wording does suggest that particular interpretation. But I believe the intent is to just avoid latin squares, period, and not determinant values arising from latin squares. Perhaps asking for a clarification is in order?
