I'll look into it, but LALR(1) support has always been a bit a dodgy in PCK. To be honest I don't know how to do it so I can't promise a fix

Describe the bug I noticed that empty rules in the pck are not handled correctly in LALR
To Reproduce Using following PCK content: programs: start whitespace: hidden
programs -> until_RUN RUN
until_RUN -> until_AT until_RUN until_RUN -> until_AT until_RUN -> until_AT -> RT until_AT -> ST
RUN= 'RUN' RT= 'RT' ST= 'ST' whitespace= '[ \t\r\n\f\v]+'
It parses correctly using the following content: RT RUN
But it does not parse correctly with the this content: RUN
while I think it should

Adding, you might have better luck with Parsley anyway. https://www.codeproject.com/Articles/5255746/Parse-Anything-Advanced-Parsley-Part-2
Unlike a LALR(1) parser you can override the parse if you have to so you can cajole it into parsing things like C# if you don't mind hand writing part of it.
