Keychain Error: Problem adding; giving up

gistfile1.txt

Getting an error after migrating to a new system when adding private keys to ssh-agent
/usr/bin/keychain -q --nogui $HOME/.ssh/id_rsa.key
* Error: Problem adding; giving up

Manually adding the key shows a permission problem
 ssh-add ~/.ssh/id_rsa.key
 chmod 700 /home/pwi/.ssh/*.key
 
In .bashrc
  /usr/bin/keychain -q --nogui $HOME/.ssh/id_rsa1.key
  /usr/bin/keychain -q --nogui $HOME/.ssh/id_rsa2.key
  source $HOME/.keychain/$HOSTNAME-sh

for me killing ssh-agent helped. I'm using wsl2 with windows 11

ssh-agent -k

killing and restarting ssh-agent helped for me too. never had this error before though, strange

i get this error more often last 2 days.
It is weird.

i use WSL too.

Same here, another wsl user, the following saved me:

eval `ssh-agent -k`
eval `ssh-agent -s`
