Is it a bug in the latest version of Backpack?

After I run composer update backpack/crud the bug... is it still there?

When I run php artisan backpack:version the output is:

@t-prod from the error I would say that it is related with some field with name defined as array. name => [array].

We removed array names, so you should replace the array with comma,separated,values.

Please have a look at https://backpackforlaravel.com/docs/6.x/upgrade-guide#step-14

Let me know how it goes.

Cheers

In addition, as noted in the upgrade guide, we heavily recommend keeping the CoreUIv2 theme during the upgrade process. Only after everything is working fine with CoreUIv2... install the new Tabler theme. Hope it helps!

Let us know if Pedro's suggestion doesn't fix the problem, and we'll reopen.
Cheers!

Unfortunately, nothing works. I made an instalkl with CoreUIV2 and I have this error :

I'm stucked :( Any ideas ?

In the index.php so I believe is linked with routes

Ok I figured it out, it's something related with config files.
So all is working fine sorry.
