Troubleshooting

Build and browser start might fail for different reasons, some being:

Database error

Similar to:

[48058:82435:0827/195241.326071:ERROR:database.cc(1821)] Web sqlite error 5, errno 0: database is locked, sql: SELECT COUNT(*) FROM sqlite_master
[48058:82435:0827/195241.326160:FATAL:statement.cc(50)] Cannot call mutating statements on an invalid statement.

If you experience something like the above, consider checking your processes and check if another browser instance is using the same profile. You can run ps aux |grep Brave-Browser-Development and check the console output. If something appears to you, try running pkill -f Brave-Browser-Development to kill these processes or consider restarting your machine and try again.
