@khanhduy62 Clone and checkout my repo. Then build yourself.

./idb_build.sh idb_companion build /usr/local/bin/idb_companion_bin
ln -s  /usr/local/bin/idb_companion_bin/bin/idb_companion /usr/local/bin/idb_companion

@djs66256 thanks for the fix, looks like something changed in the way a recent grpc version handles bytes

[djs66256]

@khanhduy62 Don't uninstall and remove the original files. Just replace idb_companion. It seems lost some dependencies. Try install again?
