Record button is missing from Chrome DevTools for NodeJS CPU profiling

Question

I was trying to use Chrome DevTools as usual for recording NodeJS CPU profiling, but this time something was different that there wasn't a record button inside the Profiler property page.

As you can see from the image below, the property page is entirely empty.

missing profiler record button

The software's versions are shown below:

chrome: Version 87.0.4280.66 (Official Build) (64-bit)

node: 10.14.2

OS: Ubuntu 20.04

Does anyone know what is going on? Or, is there an alternative way of profiling NodeJS performance without using Chrome DevTools?

This is a Chrome bug in v87+ and a fix is pending release: https://bugs.chromium.org/p/chromium/issues/detail?id=1151855

I had the same problem with a similar setup but with Kubuntu 19.10.

I rolled back chrome to its previous version (86.0.4240.75) which I got here: https://www.slimjet.com/chrome/download-chrome.php?file=files%2F86.0.4240.75%2Fgoogle-chrome-stable_current_amd64.deb.

This got me back my CPU Profiler.
