Is this in Sequoia or an earlier OS?
It appears the Tesseract code is frequently crashing with a memory corruption in Sequoia. I have no idea if this is a Tesseract bug or a Sequoia bug (the fact that it has worked fine in all previous versions of macOS does not necessarily mean the bug isn't in Tesseract).
I'm not sure that I am going to be able to resolve it though - resolving a memory corruption bug would be hard enough in my own code, it is virtually impossible in the system or in Tesseract’s code. I will look at what options there might be and whether it might be possible to update the Tesseract code, but I can't reasonably do that until my development Mac is also running Sequoia which will not be for some time. So Apple Text Recognition remains the only answer. And as you note, it is English only - at least as far as Keyboard Maestro supports, I'm not sure whether it is possible to expand it to support other languages. That is another thing I will endeavour to look in to.
