Minimal, reproducible example

const Puppeteer = require("puppeteer");
let page = "";
async function doCrawl(){
try {
  const browser = await Puppeteer.launch({ 
   
    executablePath:'/usr/bin/chromium',
   args:['--no-sandbox','--disable-setuid-sandbox']
  });
  // Create a new page object
   page = await browser.newPage();
   console.log('open new Page');
  await page.goto("site Url ...", {
    waitUntil: "domcontentloaded",
    timeout: 0,
  });

  await page.waitForSelector("#technicalstudiesSubTabs");

  await page.click("xpath/" + '//*[@id="timePeriodsWidget"]/li[6]/a');
  await page.waitForTimeout(60000)
  const riskyPoints = await getR2AndS2();
  await page.waitForTimeout(8000)
  await page.click("xpath/" + '//*[@id="timePeriodsWidget"]/li[7]/a');
  await page.waitForTimeout(8000)
  const safePoints = await getR2AndS2();
  console.log('get Points',riskyPoints,safePoints);

  return {riskyPoints,safePoints}
} catch (error) {
  console.log(error,'error');
}
 

}

async function getR2AndS2() {
  const pivotPointsTable = await page.$("#curr_table > tbody ");
  const pivotPointsData = await page.evaluate((table) => {
    const data = [];
    const rows = table.querySelectorAll("tr");

    rows.forEach((row) => {
      const values = [];
      const cells = row.querySelectorAll("td");

      cells.forEach((cell) => {
        values.push(cell.innerText);
      });

      if (values.length) {
        data.push(values);
      }
    });

    return data;
  }, pivotPointsTable);

  const S2 = pivotPointsData[0][2];
  const R2 = pivotPointsData[0][6];
  return {
    Sell: Number(R2.split('.')[0]) - 1 +'.'+R2.split('.')[1] ,
   Buy: Number(S2.split('.')[0]) + 1 +'.'+S2.split('.')[1] } 
}

Chromium does not support running as root without sandbox. See how to configure the sandbox https://pptr.dev/troubleshooting#setting-up-chrome-linux-sandbox It is recommended to create a dedicated user to run Puppeteer with a sandbox.

I did all the instructions mentioned in your link but the second problem still persists
Error: Evaluation failed: TypeError: Cannot read properties of null (reading 'querySelectorAll')
while is worked on my Linux System if not passed ['--no-sandbox']

That error means that table is null and your selector didn't find the right element on the page.

But it works in normal mode without using sandbox and this problem occurs when it is run by sandbox.
