I have a MB Pro 16" M1 Max running Ventura. I added a SSD external to use for Lightroom and formatted the the SSD MacOS extended journal. I was able to import pics to the external and view them in Lightroom. The next day while using Lightroom I received a message "drive was not ejected properly"
I've researched and see that new formats are now available but wouldn't the OS have given me an error message when I initially started using the drive.
Some drives. especially Bus-powered drives, do not deal well when the Mac sleeps and drops most USB power.
using a drive in either HFS+ Extended (which you used) or APFS (which you could have used) should not have any impact on whether a drive survives Mac Sleep without incident.
Common work-arounds include deliberately ejecting the drive before sleep, or providing external power, not just Bus power.

Try unchecking "Put drive to sleep" in the Battery System Settings.
Starting with macOS 10.13 High Sierra, APFS is the best for solid-state drives.
