Exception: "Checksum in header does not match the checksum of the content" #53

When reconnecting to the Zivid Camera (Zivid One+ M) I frequently get the following error:
Failed to initialize camera driver. Exception: "Checksum in header does not match the checksum of the content

If this happens when using the ROS package, I also get this message in Zivid Studio when I try to reconnect there.

The solution thus far has been, wait for ~30 seconds before trying again. Updating the SDK etc from v2.4.0 > v2.4.1 did not lead to a change in behavior.

Previously I have been running the SDK v1.8, where I did not encounter this problem as far as I can remember. If it did happen, it was way less frequent.

System: Ubuntu 18.04 & ROS Melodic Zivid One+ M Zivid SDK v2.4.0 and v2.4.1 Zivid Studio v2.4.0 and v2.4.1 Zivid ROS: 9b85892cbe3099a436ab17d612940669b394170a
