Older large files can't be correctly opened in MakeCode v7

[joernalraun]

From the Forums:
Since the new MakeCode version V7 the following problem occurs: When I import previously downloaded .hex files, the editor is empty and the blocks have disappeared. If I switch to JavaScript, there is only one single program line! When switching back to the block view, there are two blocks (one of which is “On start”), but nothing more. Now I have tried to save it using the “Project Link” option. However, the same problem occurs when the link is called up.
If you import a smaller new file into the editor, it works.
If you import a large older file into the editor, it also works.
So it probably affects large, new files.

Calliope version: V2
