Empyrion crashes if alt-tabbing/etc during multiplayer

I've been using ReShade with Empyrion for quite some time.  There are no problems at all in single player -- no crashes or anything, but I recently started playing a bit of multiplayer and this has become a bit of a problem.  At first I thought the issue was solely because of Easy Anti Cheat because the game would fail even to start (not even an error, just failing to even start) with EAC enabled on any version of ReShade that it doesn't like (which is why I have to keep it on an older version.)  I presume it just hasn't whitelisted newer versions yet (possibly their EAC doesn't get updated often, I don't know.)  Since online servers generally required EAC I just assumed it was getting a bit overprotective and triggering issues when graphics reset or whatever upon an alt-tab.  However, I recently started using the "local coop" option which essentially fires up a mini dedicated server in the background and it actually requires EAC to be off.  Interestingly, alt-tabbing causes a crash even in this circumstance, so I guess EAC isn't actually the culprit after all.  I also have played with someone else who used coop where the server was running on their computer and not mine and alt-tab still crashed, so I guess it is any multiplayer at all.  Interestingly I can alt-tab while it's on the initial loading screen, just not any time after.

To be more specific, it is a more proper crash where the game pops up its crash handler window for a moment before exiting when I alt-tab during multiplayer/coop rather than just simply exiting without warning.  Thankfully the server doesn't crash when I use local coop (I think it actually does use 3D or at least DirectX, but runs from a different location so doesn't pick up ReShade installed in the client folder) and I can hit save on it, so nothing is really lost.  I checked the game's logs, but I guess the crash happens so fast that it can't even log it because there is nothing indicating anything that could lead to a crash or any awareness that there is one.  It's worth noting that it crashes instantly when I hit alt-tab out of the game, not even when I actually try to switch back to it.  It also does this whether I use borderless fullscreen or exclusive.  EDIT:  I found a second log file for that session in my temp folder (why?) that did acknowledge the crash, however, there doesn't appear to be anything more useful in that log than an acknowledgement of the crash taking place.

Currently I'm using ReShade 5.4.2 (reshade64.dll as dxgi.dll in the game's client directory) as the last version I can confirm works with the game.

I forgot to say (and apparently my edit window expired?) but disabling the Steam overlay has no effect one way or the other on the crashing.
