L1app is not running on Icelake processors with ubuntu22.04 realtime kernel

We cloned the FlexRAN project from this repo. Whenever we ran the l1app, the below error is coming.
TIMER Mode
kernel.sched_rt_runtime_us = -1
kernel.shmmax = 2147483648
kernel.shmall = 2147483648
using configuration file phycfg_timer.xml
>> Running... taskset -c 0 ./l1app --cfgfile=phycfg_timer.xml
./l1app: 1: version: not found
./l1app: 2: oid: not found
size: '304651248': No such file
Cleanup after [PID] 249896

Kindly help us on how to run l1app on our cpu. We were able to compile wls,fhi_lib and fapi succesfully using icx compiler.

The reported entry point is ./l1app, launched with phycfg_timer.xml via taskset -c 0; start by reproducing that command on the stated Icelake and Ubuntu 22.04 realtime-kernel setup and capture the exact output. Compare the runtime environment with the successful compilation of wls, fhi_lib, and fapi; done means l1app starts without the shown version, oid, and size errors or the incompatibility is documented.
