Problem:
The user would like to use the Toolset portfolio module with blocks.
Solution:
The module is built with the legacy views and is not available with blocks. To work around it, activate both the block and legacy editors for Toolset, then create the portfolio with a legacy view and use it inside blocks with a View block, a "classic" or "fields and text" block.
To enable views alongside blocks, go to Toolset->Settings->General tab, under "Editing experience", choose "Show both the legacy and Blocks interface and let me choose which to use for each item I build".
Problem: A critical error is displayed when I try to import a module into my site:
"Error Details
=============
An error of type E_ERROR was caused in line 218 of the file /home/********/public_html/wp-content/plugins/types/vendor/toolset/types/embedded/classes/class.wpcf-import-export.php. Error message: Uncaught Error: Class 'Toolset_Relationship_Definition_Repository' not found in /home/********/public_html/wp-content/plugins/types/vendor/toolset/types/embedded/classes/class.wpcf-import-export.php:218
Solution: It seems that the module you're trying to import is based on the updated relationships system, but this site has not yet migrated to the new system. Go to Toolset > Relationships to migrate to the new relationships system.
