Metadraw crashes with PSMs that contains the fixed modification "Arginine amide on R, prot C-termini" Uniprot

[studentDenmark]

When I run Child scan view in Metadraw with spectra files and corresponding PSM files with the modification Arginine amide on R, prot C-termini, Uniprot, the program crashes. When I use the same PSM files from a search without this modification, it doesn't crash, and I can the fragmentation. Can you help me? Best regards
