I have been working in Block code, and after committing my work to Github, the following error appeared:

I have had this appear a few times already. There are quite a lot of functions, maybe too many for block code (I don’t know). The following are the last few lines from the console (Chrome: Version 80.0.3987.122 (Official Build) (64-bit))

Can someone offer any advice? I don’t normally code in Javascript, but I don’t mind if I have to continue that way. However, I do like coding in Blocks for the convenience.

I am having a separate issue that I am not able to able to load the game to my PyGamer, however, if I switch to Javascript, copy the entire code and paste into a separate project (which has never been published), then I can upload it.

The only problem now is is that I cannot switch back to Block code.

That’s weird! When reverting the changes made (via Github icon) which was something like the preferred editor, I was able to switch it back to Block code. 🤷‍♂️

The strange thing is that I can still code in Blocks. When I switch to Javascript, and still haven’t changed anything, then the error appears saying that the script is too large. If I ignore the changes (which there are not any) to switch back to Blocks, it works again.
