auto it is showin the Kernel error. thought i have not made any changes. i have already tried checking the Kernel.php files. more over i have already deleated the vendor and composer.lock file and install the composer . But also getting the the above error.

Moreover I also have deleted the every things that recedes on bootstrap/cache/
