@Omini yes, I just tried this way too, it still seems to cut-off at 1,000,000 bytes, so it wasn't related to breaking due to content etc, it still seems to be a data length / quota memory problem
Updated version of BAS - 23.2.1 solved most of the issues I had.
I opened backup version of project file in text editor and rebuild
it in new BAS version 23.2.1.
