"HOWEVER, the bank's IRA department kept saying that his RMD is now 'suspended' and
there WON'T be distribution requirement.... "
Apparently they think that he reached age 72 in 2023, not in 2022, they think he died in 2022 (in which case you would have a beneficiary RMD for 2023) or they are simply confused. (Unfortunately, it's quite common for bank personnel to be inadequately trained with regard to inherited IRAs.) Because your husband reached age 72 in 2022 and died in 2023, you are indeed required to complete your husband's 2023 RMD. "Suspension" of this RMD is not permitted.
[Edit: After reading Opus 17's post below, I'm wondering if the bank might just be saying that they cannot issue an RMD paid to your husband and that any standing instructions to do so have been suspended. However, you must still complete his 2023 RMD with a distribution paid to you.]
They cannot refuse your request for a distribution. You are permitted to take a distribution whether they think it's an RMD or not. It's your responsibility, not the IRA custodian's responsibility, to satisfy RMD requirements.
Sine you inherited both accounts from the same decedent, you can take the combined RMD from these inherited IRAs in any combination.
