What is preventing you from creating a new session?

I have about 620 sessions that were imported as a CSV file... So it wont be an easy task to create new sessions for each.
How do I change the connection type to Windows Terminal? Right now, if I double-click on a session, it says connecting, and then expires.

Import them again, with correct session type?
Write a script which iterates over each host entry?
What is the current session type? Is that type "Host" ?
For me when I add a Host type and open it, I get presented a list of templates to use (quick connect) like rdp, ssh, vnc, website. But even if that worked for you, I don't think that's what you'd really want.
If it were my, and I was forced to use Windows, I would add sessions of type "Windows Terminal" with "Run" command something like "ssh my_username@a.b.c.d" . Just because Windows Terminal is waaaay nicer than the built-in terminal (even if only for changing font size with Ctrl +/-) . But you'd want to also want to configure your local .ssh/config and would only use RDM to launch Windows Terminal with variable names like $hostname$.
For you, using the "SSH Terminal" session type would probably be easiest and smallest step for now.
Or, what you can do if you have "Host" entries, is add a Sub-Entry, set host and credentials to "inherited" and choose "SSH Terminal" as the session type for the sub-entry. That way you can attach different session types to a single "Host" entry.
Either way, it would always involve 620 changes (in your case) , which manually would likely be 1 minute and 20 mouse clicks for each of your 620 entries so you should definitely think about writing a script to iterate over each of your hosts from a CSV file. Devolutions provides and awesome collection of Powershell Cmdlets which can help you with that.
