Hello @Aveeva 

Please try to disable this module and try Searchanise_SearchAutocomplete :

php bin/magento module:dsiable Searchanise_SearchAutocomplete
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento cache:flush

If it start working then issue with module, but the weird part it, it was working when doing it with vendor file ?

just give it a try and let us know here .

@gaurav_harsh1  After disabled searchanise module then run di:compile cmd,

@Aveeva 

Then there is no dependency of any module, you are doing some type mistake as it is getting Improved keyword, it neither in Algorithm class nor in preference, please check in your code with this keyword.

Please share core code as well.

@gaurav_harsh1  Apart from this, anything else i need to check?

[gaurav_harsh1]

@Aveeva 

Check again by copying code to vendor (remove current preference if using vendor), is it working fine then ?

PS : add correct namespace .
