user7214: The following address uses witness version 0 and its checksum is the one expected for  bech32m addresses. However, the combination of the two is not valid.

The address was used as part of a lightning network force-close transaction and contained funds from a timed-out HTLC. My lnd node was able to spend those funds.
Is this address valid or invalid?

user208:

Correct.

and its checksum is the one expected for bech32m addresses.

No, it uses the bech32 checksum. What makes you conclude that it is bech32m?

However, the combination of the two is not valid.

Indeed. According to BIP350, witness v0 addresses must use the bech32 checksum, but witness v1 and up must use the bech32m checksum.

Is this address valid or invalid?

Valid.
