Let’s start by trying to get you on the latest version – that’s the very first release of CSIDE which is now around 8 years old! No doubt the version of ChoiceScript included in it is very behind the one you’ve download from GitHub.
Can you check below the version that you’ve got an update channel selected? You may get the infamous “SSL” error message, which I can send you a workaround for (I’ll add you to a DM).
Yeah. CSIDE sometimes gets a bad rap for things not working quite right but 99% of the time it’s because people are using an old version of it and the “bug” is that the ChoiceScript version is massively out of date. Though I’ll hold my hands up there and say that’s often on me because of the update bug I can’t fix without a tech stack rewrite (lesson hard learned). A CSIDE “2.0” would be able to fix all of this and make it very clear that users need to keep updated.
If updating you doesn’t work, then I’ll ask you to share the files, but I’m optimistic that’ll be the difference.
