Metamask & Ledger Connection

I have used metamask to stake some of my Clintex tokens (CTI) in Clintex website on one of my ledger ETH address 5 months ago. Now i have to unstake my staked tokens, I tried to do this with metamask several times. I used old version of metamask and also tried with other browsers but unfortunately, I couldn’t to do that. I know that this comes from U2F transport issues. I tried all the way I found on the internet, I also tried to use the Ledger Live bridge, but the problem still exists. Would you please help me to get this problem solved? How can I unstake my tokens using metamask and ledger?

Thanks in advance
