Problems with cert validation via CRL

Thank you for your response! I do have the trustlist.txt file on both computers - it was automatically populated with the root cert by pin entry when I imported my certificate on both machines, and it includes the "relax" keyword on both computers. There are 3 cents total in my hierarchy - root, intermediate, and mine. I've added the fingerprint of the intermediate and even my own cert to trustlist.txt to see if that would make a difference, but it didn't change anything.
The --disable-crl-checks option allows me to use the cert for encryption, so I'm pretty sure the problem lies with the crl option...there are two files (in addition to DIR.TXT) that have been populated in crl.d, and if I do a dirmngr--flush they get cleared out and are added back fine the next time I try to validate. The root cert does NOT include a CRL DP, so I've tried turning on the option not to require a crl on trusted carts, but that didn't make a difference.
I'm no expert, but when I look at the debug info (attached to original email), it appears that gpgsm is able to get the crl that my cert points to but it may be having trouble parsing it. The file itself is large, but I don't think that's uncommon, so perhaps there is a problem with the file itself. It's been updated since I started investigating, and the problem persists, so it wasn't a transient problem.
Is there a way to have gpgsm (or dirmngr?) validate that it is able to parse and interpret the CRL (or the associated .db file in crl.d) to see if that is the issue?
I appreciate your help very much. Thanks,
