UD-Q5_K_XL not recognized

Hi,
I tried to use the UD-Q5_K_XL version of Qwen3 coder next but it is not recognized by LM Studio.
The MXFP4 and the UD-Q4_K_XL are.
Am I the only one ?

Same problem for me with all the split GGUFs Q5_K_XL, Q6_K_XL, and Q8_K_XL. All Bartowski GGUFs work well though. Includes the same b7936 llama.cpp quantization changes unsloth is supposed to have in their reupload.

Thank you we are going to investigate.

Is it working again?

When I last tried Q6_K_XL I had the same issue.

same for me with Q8_K_XL. LM studio failing to read model architecture even.
all other non-Unsloth GGUF quants worked fine.
also failing to correctly read context length configuration.

for info, i have the same issue as the post just above.

edit: models seem updated but still not working properly in lm studio on 5 bits+ quantization

Bartowski ones are indeed working fine. Thanks.
