Brave can't launch / didn't close well

Description of the issue:
After closing Brave with several tabs open, I can’t re-open it. It looks like Brave is still working in the background but fails to actually close.

In my task manager (see pic below), I can see all the inactive Brave tabs. I must “kill” them with “End task” until they’re all gone, then I can re-open Brave.

After using the Task manager sucessfully, Brave ask me to choose a user and then it opens. When Brave starts, I got a message in Brave on the right corner saying “It looks like Brave didn’t close properly” (or something like that).

Steps to Reproduce (add as many as necessary): 1. 2. 3.
I don’t really know. Maybe open many tabs and close directly Brave without closing the tabs one by one.

Actual Result (gifs and screenshots are welcome!):
all the inactive Brave tabs in background, that must be killed in order to re-open Brave

Expected result:

Reproduces how often:
Maybe one or twice a day, depending on how i use Brave.

Operating System and Brave Version(See the About Brave page in the main menu):

[Version 1.9.80 Chromium: 81.0.4044.138 (Official Build) (64-bit)]
