tried Application bypass in forcepoint management
What does that look like - what files and such are you 'white-lising'. I would like to know more about the process for doing so if you have documentation / links of how this is done in Forcepoint.
Tha said, the problem could be that Fences runs in the Win Explorer process. Perhaps an exclusion (just as a test) of Windows Explorer itself (if possible - again, I have no idea how the exclusion process in Forcepoint works) could yield some interesting results.
