Good day!
I was learning to create projects on basic platform games and the cloning of sprites.
I have encountered problems such as the sprites being non-responsive, slow response time and the recurring of the following message:

A JavaScript error occurred in the main process
Uncaught Exception:

I do not have any knowledge in scripting. I wonder, what could be done to solve this problem?
Thank you.

What's your Browser/OS

Good morning.
My browser / operating system: Windows NT 10.0, Chrome 73.0.3683.86, No Flash version detected

I am using Google Chrome to download the Scratch Desktop installer. Normally I will work with the offline editor and then upload the projects later.
I am using Windows 10, Acer Swift with Intel CORE i5.

This is the link to the print screen of message:
The Print Screen of Error Message

I was trying to create the following projects:
gold fish
testing platforms

Thank you.

Hi, I have tried to use Scratch 3.0 for desktop on another laptop, the Acer Aspire F15, Windows 10. The same problem persisted.
From time to time, I couldn't save my project which it became complicated with numerous algorithms executed via several sprites.
It happens to both of my Acer Swift and Acer Aspire F15.
I wonder how this problem can be fixed.
Thank you!

Apparently, the part with “resource blocked or busy” points to that you can't access the offline editor. The rest basically lets you know which lines and files are broken. Did you accidentally mess with the installation directory? Have you considered reinstalling Scratch? I'm writing this with an Intel Core i5 so your processor is definitely not a problem.

please help

Please create your own topic instead of necroposting; it's more beneficial to you and to everybody else.

Maybe you can try reinstalling it or uninstall it and install it again

I've had the error too and believe I know the answer! I have downloaded it from the microsoft store and got the error, but if you download it from scratch (shown at very bottom) this should fix it. I hope this helps
