Raspberry Pi CM4. Is it possible fstrim deleted/corrupted needed files?

I have a problem. On my device (Raspberry Pi CM4) my programm uses /var/opt directory (files created/downloaded manually). After some hard reset my program cant see couple of files, I go into the log and see these rows: Aug 22 12:23:26 systemd: Starting Discard unused blocks on filesystems from /etc/fstab... Aug 22 12:23:26 fstrim: /: 1.7 GiB (1784496128 bytes) trimmed on /dev/mmcblk0p2 Aug 22 12:23:26 fstrim: /boot: 204.5 MiB (214468608 bytes) trimmed on /dev/mmcblk0p1 Aug 22 12:23:26 systemd: fstrim.service: Succeeded. Aug 22 12:23:26 systemd: Finished Discard unused blocks on filesystems from /etc/fstab. After these rows, in this time of boot my program broken (needed file was not found). Is it possible that fstrim deleted my files? I dont see any other reasons from logs. I did see these rows earlier (another date): Aug 19 00:06:01 systemd: Starting Discard unused blocks on filesystems from /etc/fstab... Aug 19 00:06:01 fstrim: /: 389.6 MiB (408547328 bytes) trimmed on /dev/mmcblk0p2 Aug 19 00:06:01 fstrim: /boot: 204.5 MiB (214468608 bytes) trimmed on /dev/mmcblk0p1 Aug 19 00:06:01 systemd: fstrim.service: Succeeded. Aug 19 00:06:01 systemd: Finished Discard unused blocks on filesystems from /etc/fstab. But after them all was OK.
