server unstable when listenling to udp socket

[AcThPaU]

esp.connect_AP(secrets["ssid"], secrets["password"])

sock = pool.socket(pool.AF_INET, pool.SOCK_DGRAM) # UDP socket
esp.start_server(1984, sock._socknum, conn_mode=1)

while True:

Hardware: pyportal
NINA version: 1.7.7
CP version: 9.1.0 beta3
esp32spi version: frozen

a client is constantly sending udp packets to the host address

after a few minutes n_bytes is always zero, and in some occasions TimeoutError: Timed out waiting for SPI char

it's esp32spi library issue, the one frozen in pyportal 9.1.0 beta3 is buggy. ver. 8.3.1 works fine.

TimeoutError: Timed out waiting for SPI char issue still present, it happens randomly from 30minutes to 12hours.
