@zeozeozeo seeing the panic, what was the last thing you did when you edit your source code? (example: did you add two characters or deleted a word)

this would help me reproduce the error and solve it. thanks :)

Just tried it again and the error happened when I added a few characters or a new line.

Can confirm that, having the same issue with me too.

@kiwimoe @zeozeozeo Hi, sorry for the late response was on a break. I have encountered issues on my side and fixed it in https://github.com/vlang/vls/commit/5251fe7c586f083e6474a9dccd0928a1e4e29385 . Let me know if it fixed your issues before we can close it. Thanks! 😃
