I think that the amount of small transactions is the problem here. Hardware wallets like Trezor aren’t meant to be a receiver of so many small transactions of Bitcoin. Instead, you should accumulate the sats rewards in a software wallet or exchange account until the amount is larger (maybe ca. $1,000) and then transfer that amount to the hardware wallet.
I don’t know what the typical amount in sats you get from the mining pool and I have no idea about the memory size in Trezor T, so I can’t calculate how large sum you can transfer out either. However, you should try and transfer smaller amounts to a software or exchange wallet and then transfer the large sum back to Trezor, thereby getting rid of the small transactions.
And change the address you receive sats from the mining pool to a software wallet, for instance.
Maybe Community support have a better idea. You’ve posted your ticket ID above so they’ll contact you. This is solvable but may take time and manual work before it’s fixed.
