MacBook Air extremely high CPU load and overheating

Ok, that would be the summary page. What would really be helpful is if we can get a copy of the report. The link I provided you tells you how to create it and send it with your reply.

Looking at the image you provided, the report will be the last icon on the left side.

1. Select it.
2. Then from the top of the app, select Share report.
3. Select OK. This will place a copy of the report in your queue.
4. Then create a new reply here, and then, use the "Additional text" tool in the forum's editor.
5. Paste the just copied report into new text box that will appear.

Let's start with the last item - heat. The 2022 M2 MacBook Air is known to run "hot." It relies on passive cooling (no fans), and has been designed with a minimal amount of passive cooling ability beyond thermal paste & graphite tape. Even the Mac's logic board shield does not employ a heat spreader. My suggestion is to get a laptop cooler and use this, especially on warm-to-hot days.

Just to let you know ... Google Chrome is a known memory "hog." If you prefer the Chrome user interface, but do not like Apple's Safari, I suggest that you try the Brave browser.

The "Google Chrome Helper (Renderer)" is essentially a bridge between your Chrome browser and external content, such as third-party plugins or embedded video players. In theory it facilitates the smooth operation of these components within your browser. However, at times as you can see, it can consume significant CPU resources, leading to system slowdowns.

I don't think that is the case here. I suggest that you completely remove Google Chrome and all of its artifacts and try using another browser. I already suggested Brave, but Safari or FireFox should do equally well.

Then you can use Activity Monitor's CPU & Memory tabs to see if there is any improvement ... there should be with Chrome out of the picture.

Another thing you can do, that would help us get a better understanding on what your Mac is doing, is to run an EtreCheck report, and optionally post it here if you need assistance with interpreting its results.

You can certainly take your Mac to your local Apple Store. Whether or not they will replace it will depend on what they found and could repair. If you prefer to go this route, then you can ignore my previous reply.
