I'm unable to activate both Toolset Blocks and Toolset Views plugins simultaneously.
Solution:
Toolset Blocks and Toolset Views share the same codebase, so having both activated isn't feasible. Deactivate and uninstall Toolset Views; Toolset Blocks inherently include the older functionalities. To access the classic views within Toolset Blocks, follow the steps in "Toolset > Settings > General" and enable legacy views.
