You installation was corrupted, i.e. it was missing a gen_snapshot binary which otherwise should be present. This for example might be caused by antivirus software quarantining it - so if you are using any antivirus software I suggest you exempt flutter installation folder from scanning.

Then you copied an ARM64 gen_snapshot over to the place where ARM gen_snapshot lives. These two binaries are completely different and can't be just copied like that - that's why you hit a problem.

Instead you should remove cache folder entirely (it is located in F:\Android\flutter\bin\cache judging by the output you posted), then run flutter doctor - which would download all artifacts again. As I said before you would need to watch your antivirus - if you are running any - and make sure that it does not randomly remove parts of the Flutter installation.
