is there a tool to recover corrupted fastq files

So I have several fastq files of a BS-seq assay and most of them are corrupted, some reads either don't have a header or the third line (the line with + ), since the files are quiet large, I don't think I could recover them with typical commands in linux. So I was wondering if there is a tool that removes only the corrupted reads.

Thanks in advance

You can use seqkit sana to remove malformed entries, and optionally seqkit pair afterwards if it's paired end data to match up the remaining read pairs.

You may also want to give a try to FastqWiper (https://github.com/mazzalab/fastqwiper)
