The user limit on the total number of inotify watches was reached; increase the fs.inotify.max_user_watches sysctl
how to fix this:
sudo sysctl fs.inotify.max_user_watches=524288
to persist the changes, edit /etc/sysctl.conf and add:
# sysctl settings are defined through files in
# /usr/lib/sysctl.d/, /run/sysctl.d/, and /etc/sysctl.d/.
#
# Vendors settings live in /usr/lib/sysctl.d/.
# To override a whole file, create a new file with the same in
# /etc/sysctl.d/ and put new settings there. To override
# only specific settings, add a file with a lexically later
# name in /etc/sysctl.d/ and put new settings there.
#
# For more information, see sysctl.conf(5) and sysctl.d(5).
fs.inotify.max_user_watches = 524288
