Inconsistent sequence and quality lengths in FASTQ files created by SortMeRNA

Description of the bug

This issue was discussed in SortMeRNA repository already (https://github.com/sortmerna/sortmerna/issues/407).

STAR failed for one sample due to the sequence and quality lengths mismatching for a read. After TrimGalore I have this

@ST-K00265:389:HMJW3BBXY:1:2223:9039:32244 2:N:0:ATCCACTG+ACGCACCT
ATAAAGTTGAAGGCTACAAGAAGACCAAGGAAGCTGTTTTGCTCCTTAAGAAACTTAAAGCCTGGAATGATATCAAAAAGGTCTATGCCTCTCAGCGAATG
+
<A-AFF<FJJFFF<AAFJJ<FAJFF<JFFF-JJJJJJJJJJJ7JJJJJFJJFJJJJJJJF<JJJF<JFJJJFAJJFFFFJFJJJJAAJJJJJJJJJJJFAA

which becomes this after SortMeRNA:

@ST-K00265:389:HMJW3BBXY:1:2223:9039:32244 2:N:0:ATCCACTG+ACGCACCT

I had to deactivate the SortMeRNA step to make it work.

Would it be possible to add a failsafe for FASTQ integrity after each step that generates a FASTQ file? If necessary, fix the FASTQ file on the fly? I suggest this as a general solution.
