Brave has locked the profile so that it doesn't get corrupted. If you are sure no other processes are using this profile, you can unlock the profile and relaunch Brave.

と言われ,起動しない.
原因
PC名を変更後braveが強制終了してしまったことにより,プロファイルロックが残ってしまったため.
解決
ロックファイルを削除すれば良い.
~/.config/BraveSoftware/Brave-Browser/SingletonLock が問題のファイルなので
rm ~/.config/BraveSoftware/Brave-Browser/SingletonLock
を実行する.
感想
強制終了でロックファイル周りが残っちゃうってlinuxあるあるですよね, むやみにしてはいけないね...(当たり前)
