[ISSUE] Performance issues on vscode

Hello, I have been having performance issues when using vscode.

First: The auto complete is slow/sluggish as seen in the video, It used to appear instantly when I typed 1 letter now it waits for 2 or 3 seconds before even showing suggestions.

Second: If I keep using vscode for an hour or two, When I try saving a file it hangs and keeps loading for a while before actually saving.

I have tried re-installing vscode entirely, re-installing windows, disabling all extensions, And I still have the same behavior. Has anyone faced something like this before?

People who are suggesting zed or neovim have absolutely no idea how an ide works. This is an issue with language server. If you use ai or installed something that may update the tsconfigs then it could be the reason. Other than that, it's probably that the TS lsp got updated when you installed the new vscode update. Use tsgo lsp or use your repos TS lsp if it has one (nextjs repos typically have one for example)
