My info is not very recent, but few years ago I analysed structure of data and structure file. There are many auxiliary structures, but actual data are stored in blocks, where each block have a prefix, containing, between other, size of the block. If this field got corrupted and contained some ridiculous big value, 4D would crash when reading the data with the "Attempt to read beyond end of file ..." error, This error was hard to fix, because restore did not help (when it did not read content of blocks) or crashed as well (when it did.) When problem was in data file, error happened when 4D accessed particular record, then it was possible to find that record in file and fix it with hex file editor. With structure this would be much harder. So, if this is the case, I am afraid you probably do not have other solution then go to stable backup and then try to copy changes, if you can open structure without crash. What I would suggest is to try to exclude all other sources of problem, maybe moving the structure to new empty folder, no plugins, components, settings or logs.
