Issue#4 Resolved but the dumped memory couldn't be analyzed using crash

#5 : Resolved the issue 'main' panicked at 'assertion failed

However, I am not able to analyze the dump using crash. The vmlinux file was generated according to the running kernel. Two versions of crash utility were used for testing and none of them were able to read the dump (even by providing System Map), though live analysis using crash and the vmlinux works. Error : crash: read error: kernel virtual address type: "page_offset_base", which means the dump was not generated correctly. Tried with multiple dumps and same error.

I suspect the generated dump has an integrity issue. Any help, would be great.

Command:
crash -S -d 300 /usr/lib/debug/lib/modules/uname -r/vmlinux dumpit-linux/target/release/kcore.dumpit.4.18.0-425.10.1.el8_7.x86_64.2023-01-30-0112.core
