Q) Are there any editors opening like asset manager or Script editor.
Here is the system and scenes folder from the original installation, lets see if this fixes it

Download:
Just copy both folders inside the Zip and place onto the root of data, overwrite when given the choice.
Also, i cant remember your computer specs. Would you mind adding them here

Hopefully, we can get all these errors out of the way so they do not rear their head when we go for a full release
