  ╰─▶ Because only the following versions of grpcio-tools are available:
          grpcio-tools<=1.71.0
          grpcio-tools==1.71.2
          grpcio-tools==1.72.0

          grpcio-tools==1.80.0
          grpcio-tools==1.81.0
      and grpcio-tools>=1.71.0,<=1.71.2 depends on protobuf>=5.26.1,<6.0.dev0,
      we can conclude that grpcio-tools>=1.71.0,<1.72.0 depends on
      protobuf>=5.26.1,<6.0.dev0.
      And because grpcio-tools==1.72.0 was yanked (reason: Yanked due to issue
      with MacOS wheels), we can conclude that grpcio-tools>=1.71.0,<1.72.1
      depends on protobuf>=5.26.1,<6.0.dev0.
      And because grpcio-tools>=1.72.1,<=1.73.1 depends on
      protobuf>=6.30.0,<7.0.0 and protobuf>=6.31.1,<7.0.0, we can conclude
      that all of:
          grpcio-tools>=1.71.0,<1.78.1
          grpcio-tools>1.78.1,<1.81.0
      depend on one of:
          protobuf>=5.26.1,<6.0.dev0
          protobuf>=6.30.0,<7.0.0

      And because grpcio-tools==1.78.1 was yanked (reason:
      https://github.com/grpc/grpc/issues/41725) and grpcio-tools==1.81.0
      depends on protobuf>=6.33.5,<7.0.0, we can conclude that
      grpcio-tools>=1.71.0 depends on one of:
          protobuf>=5.26.1,<6.0.dev0
          protobuf>=6.30.0,<7.0.0

      And because codetanks-viewer:dev depends on grpcio-tools>=1.71.0 and
      your project depends on protobuf==7.35.0, we can conclude that your
      project and codetanks-viewer:dev are incompatible.
      And because your project requires your project and codetanks-viewer:dev,
      we can conclude that your project's requirements are unsatisfiable.

hint: Pre-releases are available for `grpcio-tools` in the requested range (e.g., 1.81.0rc1), but pre-releases weren't enabled (try: `--prerelease=allow`)
