Is error is related to butterknife library as it says that
the given artefact contains a string literal with the package reference androidx.support.v4.content that cannot be safely rewritten libraries using reflection such as annotationprocessor' needs to be updated manually to add support for Androidx

Can you give your stacktrace
Do have a look on readme file on how to build the app and do try delete .gradle , .idea and try rebuilding it also do check Build variants to kiwix debug
Also if not latest do try after updating your Android studio
Use butterknife 10.1.0
@abdulwd Would you be able to have a look to this please? The ticket is unclear to me and it seems there is already a PR... but not sure we have a bug here at all.
@gptshubham595 ok wait trying all those
@gptshubham595 thanks it resolved
@gptrohit @gptshubham595 @abdulwd What about the PR #1139?
I just updated the versions
And saw that he was reporting error related to butterknife version which is written 8.8.1 hopefully he would be using old version
So, and also it worked for him i think
Yes on updating butterknife version it resolved mines thankyou @gptshubham595
