Error unstaking ABPT v1 - UNPREDICTABLE_GAS_LIMIT

I had completely forgot about this pool I had staked and want to unstake it now (not migrate), however I keep getting an error message when entering any amount:

This is the message when clicking on “copy the error” (wallet address edited):

I’ve been trying on different dates and times, no joy. Any suggestion other than migrating it to V2?
