bored with getting "You have launched an older version..."

First, let me describe the configuration I have been using successfully for two decades -

I am on the latest release channel release with a POP3 configuration.

I keep the message store on my file server and have Tbird installed on it and my laptop. The file server is a Win 11 machine as is my laptop. Each machine points to the message store (including the config file) on the file server.

Of late, every time I try to use Tbird on the file server, I get "You have launched an older version" message. So far reinstalling and pointing to the existing message store works.

But I am getting bored with having to reinstall every time, and I suspect this will eventually break completely.

Is there a way to stabilize this?

Thanks Jonathan

Are all clients using the same version of Thunderbird? Are you sure that only one of them is accessing the profile at a time?

Yes as to versions (specifically, the file server has the most recent update).

And yes, I get a very different response if Tbird is open on one machine and the other tries to open
