### Please describe the problem.
When enabling an S3 remote with hybrid encryption, I get a file locking error:
```
$ git annex enableremote s3remote
git-annex: .git/annex/creds/__S3_REMOTE_UUID_REDACTED__: openFile: resource busy (file is locked)
```
I can confirm that this happens when no previous process is running (and lsof shows nothing open before running enableremote), for example in the motivating case here of cloning to a new, freshly-mounted HDD.
If I copy the `.git/annex/creds/__S3_REMOTE_UUID_REDACTED__` file from an existing clone of the repository to this new one, then enableremote works fine.
```
$ git annex enableremote s3remote
enableremote s3remote (encryption update) (to gpg keys: HEXREDACTED) ok
(recording state in git...)
```
### What steps will reproduce the problem?
For me, with a source a repository that has a pre-configured S3 special remote:
```
$ git show git-annex:remote.log
__UUID__ bucket=bucket-name cipher=__base64_jibberish__ cipherkeys=GPGKEY_HEX datacenter=US host=s3.eu-central-003.backblazeb2.com name=s3remote partsize=512MiB port=80 protocol=https s3creds=__base64_jibberish__ signature=v4 storageclass=STANDARD type=S3 timestamp=168000000.0s
```
Then, to reproduce this:
```
git clone /path/to/established-repo new_clone
cd new_clone
git annex init new_clone
git annex enableremote s3remote
```
### What version of git-annex are you using? On what operating system?
The latest:
```
$ git annex version
git-annex version: 10.20230926-g44a7b4c9734adfda5912dd82c1aa97c615689f57
```
### Please provide any additional information below.
### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
A great deal, we use it daily in our research and I also use it on some personal files -- thanks for all your efforts Joey et al.!
