Desperate. Swaps failing 24 hrs. “The contract function “approve” reverted”.

I've never had any problems with using Uniswap plenty of times before. I'm using with Coinbase wallet connected to Ledger as always. Error was "The contract function "approve" reverted".. I've been stuck for 12 hours no progress. Once the Coinbase Wallet pops up and I click "approve", there is the instant error and nothing reaches the Ledger wallet for approval. No change on Ledger, it appears to not even receive the request, it just rejects as if Ledger is not connected. Everything works fine on Solana chain. I deleted the Ledger ETH app and reuploaded, same result.

afaik everything is correct: Ledger is open with ETH app open "Application is ready". Settings: blind sign enabled, everything else disabled. Ledger Live app is closed. No other app is using the Ledger. Eth for gas is avail in wallet. Uniswap is connected to Coinbase Wallet, showing correct address and correct existing balances in swap window. Coin balance is available for swap. I've deleted cookies, closed/opened tab, cycled tab, disconnect/reconnect ledger and CB wallets over and over again all day. No "pending transactions" Can't connect to UNI discord.

Same result when I tried on Sushiswap.

The input is not reaching Ledger, even though it's plugged in and updated.

Any suggestions on what to try? This is absolutely maddening. Thanks!
