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) 22305:0421/ 034620. 183967: ERROR:CONSOLE( 1)] "Uncaught TypeError: Cannot read property 'Runtime' of undefined", source: devtools: //devtools/ bundled/ root/root- legacy. js (1) 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.
