Hi @Patrick_C,
What you’re trying to achieve is basically a downgrade and it is not supported straight forward.
As noted in this question, quoting Matthew
We don’t follow any particular release schedule. Each time a new community version is released, we must manually merge all changes from upstream with our own changes. This takes time. How much time is dependent on how many backwards-breaking things MySQL introduce in that version.
That said, looking at release dates for past versions, it should release by end of this month but don’t quote me on that 
If you cannot wait, your only straightforward option is use logical restore to the 8.0.32 PXC.
Thanks,
K
