Listing versions by Data Source within the Table of Contents against a branch versioned service with over 18,000 thousand branch versions using the 'Change Version' or the 'Manage Versions' option, receives error "Cannot connect to datasource"

Workaround

Make a direct connection to the database via Catalog in Pro > Right click on the database connection > Geodatabase connection properties > Switch to Branch Version Type > Right click on the database connection again > Click Versions > All branch versions are listed (this takes a few minutes)
