Turn it off by adding trimCache="false" to the cache setting in the ImageProcessor cache.config:

<cache name="EpiserverAzureBlobCache"... trimCache="false" />

Note

Exception is related to ImageProcessors trim of its cache and for some reason encounter an issue,
as this is a 3rd party add-on which also now seem to be a retired project by its developers and the issue logged on github for this is gone due to retirement I do not see that it will be investigated by them so the only option is to turn of the cache trimming.
