Xcode build failed due to concurrent builds

Question

I am using flutter version 1.22.6, I have already published my application and have to make minor changes in my application that is why I do not wish to upgrade flutter sdk in my application. But when I try to build my application it says:

Xcode build failed due to concurrent builds

It pops up till some time and then it displays the error:

unable to attach DB: error: accessing build database
database is locked Possibly there are two concurrent builds running in the same filesystem location.

I have tried the solutions such as closing the Xcode and building only from my VS Code editor, also tried flutter clean and then build. Can someone help me with this if I do not have to upgrade flutter?
