Visual Studio Code保存文件时代码错乱损坏，求助原因与解决办法

今天在Visual Studio Code中保存文件时，代码突然完全错乱。该文件已正常使用两周，此前从未出现过这类问题。错乱不仅导致代码格式混乱，还产生大量语法错误。

保存前后对比 #

保存前 #

整洁的代码格式：

async function listEmails() {
            let response;
            try {
                response = await gapi.client.gmail.users.messages.list({
                    'userId': 'me',
                });
            } catch (err) {
                document.getElementById('content').innerText = err.message;
                return;
            }
            const emails = response.result.messages;
            if (!emails || emails.length == 0) {
                document.getElementById('content').innerText = 'No emails found.';
                console.log('No emails found.');
                return;
            }
            // Flatten to string to display
            const output = emails.reduce(
                (str, email) => `${str}${email.name}\n`,
                'Emails:\n');
            document.getElementById('content').innerText = output;
        }

保存后 #

代码格式错乱且充满错误：

async f        Emails() {
            let response;
            try {
            response = await gapi.client.gmail.users.messages.list({
                'userId': 'm                            } catch (err) {
                document.getElementById                t = err.message;             ret             }
                     = response.result.messages;
            if (!emails || email            
               um        ntById('content').innerText = 'No emails                      console.log('No emails f                     return;
            }
            // Flatten to string to                 const output = emails.reduce(             (str, e        st        me}\n`,
                'Emails:              document.getElementById(            Text = output;
