Salvaging an overclustered run

I recently sequenced a 16S V3-V4 library with a MiSeq v3 kit. Unfortunately, the run was badly overclustered and the reads passing filter were very low.

I'm going to buy another kit, but in the meantime I'm hoping to salvage what I can from this run. My denoising stats are pretty poor and most of my sequences are failing to merge. Does anyone have any tips?

Hi @areaume,
Can you provide some additional info?
Can you send in your stats.qzv?
What commands are you running?
