You might have an empty net6.0 folder in gui/bin/debug that is acting as bait. happens when you switch between versions. maybe you could look and delete and retry?

In PeptideSpectralMatchTest, line 36 should be changed to string

pairedTargetDecoyHash = null;

to be compatible with the current master of mzLib

[elaboy]

can you target both net 6.0 and net 8.0?
