What do you mean with "pin"? Installing an old version of python3-keyring
(without the chainer) by pinning the ("old") DEB package (version)?

TLDR:

"chainer" is new and a "meta keyring" that decides internally which actually
installed
keyring will be used using some heuristics.
"chainer" is not supported by BiT since the heuristics may choose another
keyring in the future for any reason
and the wrong keyring is used then (which does not contain the stored
credentials for BiT).
To solve (work around) this problem add a keyring config file to specify
("pin") which keyring you want
to use instead of chainer, see these instructions here:
https://github.com/bit-team/backintime#non-working-password-safe-and-bit-forgets-passwords-keyring-backend-issues
-> Just use your prefered keyring in the config file:
default-keyring=keyring.backends.SecretService.Keyring
In full length:
---------------
To really use a a keyring two things must be installed:
1. A supported keyring software (debian package)
2. A python library that has a "driver" to enable the keyring of 1. for python
The BiT logs show that "secret service" is installed (satisfies above number
1.):

The BiT logs also show that above number 2. is satisfied
("python3-secretstorage" is installed together with "python3-keyring" AFAIR
since it has a "depends" relationship):
> DEBUG: [common/tools.py:899 keyringSupported] Available supported backends:

Since newer "python3-keyring" versions use "chainer" by default now (which is
not supported by BiT) no keyring is available in BiT:

Outlook:
--------------
I think I should add a link to above "known issues" section to the debug output.
How the chainer issue could be fixed is described quite well in this feature
request (add a GUI to select the keyring):
