149.0.2 is no better.
Tab unloader is completely broken, unloaded tabs won’t be discard but hold in shared web process and reload right away. 148 did it too but won’t be a dick after you kill those shared processes they won’t come back.
Extension process start bloating right away can eat 10+GB ram if let alone. And browser window would freeze way before that. Kill extension may un-freeze the window but data transmit won’t resume.
All in all it dead on launch.
