Analysis doesn't work

Could anybody tell why local stockfish analysis doesn't work recent time?

When I turn on local computer evaluation
for variation analysis there is status "loading engine" and there aren't any arrows for recommended move

Hello,

Can you please open your browser dev tools (Ctrl+Shift+i) and look in the console for error messages? A screenshot of it would be great.

Thanks!

Recently I have had the engine crash after adjusting the number of cores and the number of variations in the settings. It says something like stockfish crashed so I reload and most of the time it works again just annoying.

Hello, Thibault.
I'm sorry, but can't embed image in message. The text in console is:

Thanks. This helps a lot, already. What's your Chrome version? (Menu -> Help -> About Chrome)

Hello.
The version is 53.0.2785.116 m
I think I need to update Chrome. It suggests.

#7 Its always easier for the developer if you are updated. Do it and see if the error is still there. Sometimes, browsers also have bugs.

I have updated to 53.0.2785.143 m
The problem is still here
Console log is:

Put this in chrome URL bar:

chrome://components

What version is the "pnacl" component? For instance mine is 0.54.41.1881
