Failed to read definitions file

[BlesterBlade]

I keep getting this error when opening visual studio on my laptop which causes me to get alot of typeerrors. I tried disabling then enabling luau extension, replacing the file with a new one. But none of them worked meanwhile on my pc it works completely fine without errors.

I tried to switch to the older version uninstall and reinstall that didn't work then i downloaded the link and put it inside the GlobalStorage folder and it still gives me those errors

Second url opens a site with a lot of code in it, do i have to do something with that?

I started getting this error too, couldn't find any solution.

I've got this same problem in the middle of the day 2 days ago, across 2 different devices (Windows PC, Mac laptop), out of nowhere. Seemingly no updates were pushed to both luau and luau-lsp, and even my outdated Neovim setup was breaking too.
I've replaced the type files multiple times, done multiple restarts, changed directories, and ensured the files have read access, and yet still the same bug.

I'm not sure if this will help but I ran into the same issue recently, I found that I had Fflag sync disabled and when I enabled it the error somehow went away. Again this was just in my case, but it may not work for you.

I noticed it after you mentioned it. When I don’t get the “Failed to fetch current Luau FFlags: TypeError: fetch failed” warning (which happens when it can't connect to Roblox, etc.), I don’t encounter this error and the unloaded types are loaded correctly. However, when I open VSCode without an internet connection, I get both this warning and the error.

On Saturday we renamed class to extern type in the type definitions to align with new Luau syntax expectations: 6db0f31

However, it looks like parsing is still behind a flag
LuauDeclareExternType. If you do not have flag syncing enabled, or it is not working, then it would break the syntax.

I will revert this change due to this issue and wait until Luau removes the flag

Reverted, please run the Luau: Redownload API Types command in VSCode to fix this

This issue appears to be fixed now. Can anyone else confirm? If so, should might consider closing it.

Closing as completed, please feel free to open a new issue if you are still experiencing problems
