First, I mistakenly deleted my Flutter SDK folder. Then, I reinstalled it with the new version SDK from flutter.dev but forgot to remove the config files and cache before reinstalling. Now, every Flutter project (including examples) builds for Linux will encounter this error, but web builds are fine. After that, I deleted the SDK and removed all config and cache files to reinstall, but it didn’t run.

I changed my Flutter channel to main, but it didn’t solve the issue.

I also tried to reinstall the Flutter SDK using pacman, but encountered another error:

Methods from comments on this ：https://aur.archlinux.org/packages/flutter-tool, couldn’t solve the issue.

I’ll soon reach my deadline. Thank you very much for your help.
