Running the old, saved linux-image-6.1.0-34-amd64 kernel package (kernel 6.1.135-1) - selection via grub - , the situation doesn't occur and the resumes are solid now. Note that I didn't upgrade or install any other packages in between, only using a different Linux kernel from Debian, and now the situation doesn't occur anymore.

Thanks for your report.

Can you please report here a full boot long once triggering the issue
with the 6.1.140-1 please from boot, to suspend and then resume.

Your system appears to be tainted furthermore with
TAINT_PROPRIETARY_MODULE and out of tree modules, so we need to se as
well what those are.
