Big Sur and Messages No Text Entry Field
For each affected contact (I only had one, so I have no idea if multiple contacts present different problems):
(0) Have Messages open, but have the active conversation be one of your working contacts, NOT one of your broken contacts (not sure if this matters, but this is what I did).
(1) Open something in Preview (an image, pdf, whatever).
(2) Click the sharing button (box with an up-arrow coming out of it).
(3) Select Messages
(4) Enter the contact's name (duh)
(5) Enter some text in the provided box
(6) Send
(7) Check your Messages conversations that were broken.
(8) Rejoice
A quick fix for this, albeit not permanent, is to react to any message in the thread (i.e. thumbs up, thumbs down, heart). This will quickly reinstate the input.
The only other thing I think might be worth a shot is somehow removing all message history from you Mac, essentially so it's totally clean (as if messages has never been setup) and then resync with iCloud messages. Does anyone know how to do this? Where all the associated files and preferences are located?

@mikeportanova's solution: share an item with the contact
@ozwoz's solution: do a tap-back reaction to an item in the contact's feed
My own previous solution: Click the button to start a new conversation, and find the person's iMessage contact result. This will start a new conversation thread, but it will have all the old conversation in it, and will have the message input field at the bottom.
Thanks for this help!
I'm in the same boat as @M_Prewitt...
tried sharing an item with contact... works temporarily
need to try doing a tap-back reaction... that might be the quickest solution.
I've been starting a new message and then adding my wife's name, then starting a new message that way... the reply box appears... temporarily.
I'm on Sonoma 14.6.1 and this problem still persists. The above have not worked for me. For clarity, mine is a group chat. When I tried the "preview" solution and select messages and it starts a new message altogether, but when I type the name of the group text, it defaults back to the group itself, without keeping the preview item (and there is still no text box). I cannot react to any of the messages in the group chat (i.e., there is no Tapback option).
I can apparently delete and start a new text thread, but then I lose all of our previous conversation topics, which is a shame and pretty annoying. This is the second time this has happened for me. Additionally, I will say I use iCloud to share messages across an iPhone 13Pro and a "gently used" MacBook Air, early 2015 running Monterey 12.7.5 (and running quite well, I might add!).
Love the products, just this quirky issue has been a pain in my side. ;) Thanks in advance for any thoughts.
I am having the exact same behavior as @mdourney described. It's a group chat with a lot of history, it works on my iOS devices just fine but there is no text input or react options in message on MacOS 14.6.1
