I can reliably reproduce the problem with chromium-browser 84.0.4115.5-0ubuntu0.18.04.1 from the dev PPA (ppa:chromium-team/dev). The relevant error messages are:
[22305:22305:0421/034620.183897:ERROR:CONSOLE(1)] "Uncaught TypeError: Cannot read property 'Runtime' of undefined", source: devtools://devtools/bundled/root/root-legacy.js (1) [22305:22305:0421/034620.183967:ERROR:CONSOLE(1)] "Uncaught TypeError: Cannot read property 'Runtime' of undefined", source: devtools://devtools/bundled/root/root-legacy.js (1) [22305:22305:0421/034620.185275:ERROR:CONSOLE(70)] "Uncaught TypeError: Cannot read property 'setInspectedTabId' of undefined", source: devtools://devtools/bundled/devtools_compatibility.js (70)
Note that the chromium snap in the edge channel (version 84.0.4115.5) is not affected, devtools function correctly.
