Failed To Decompress Error On Startup

[Cosmo]

Issue Type (Required):

Crash - on Launch

Issue Description (Required):

I had no trouble running the game yesterday, however I downloaded today’s hotfix (1.11.5) and started the game, and I’m now met with a continuous ‘Failed to decompress’ error upon pressing space to load into the operative selection screen. I have updated my Nvidia drivers and verified the game, however it still results in a crash.

The three console logs are present because I seemingly couldn’t delete them, so the 40.8 KB one is associated with the crash report.

I noticed that the ‘building shader cache’ window hung on 98% for a few seconds on the first startup, and took longer to progress after installing new drivers (the latter is understandable).

I want to note that I had a similar issue in 2024, relating to the Vmin shift issue in my 13900K/14900K CPU:

[It's Been Fun] Failed To Compress consistent crash

Issue Type (Required): Crash - During Play Issue Description (Required): For the past week or so I get a “failed to compress” notification (pictured) every match I play. It’s happened well into the match, a few minutes in, as I launch the game and hell, once it happened on the loading screen back to the Mourningstar. I’ve looked it up, and tried multiple things (verifying doesn’t work. I’ve moved it to a different drive, still nothing) Apparently I’ve got an Intel i7 13700k but not Intel XTU so…

There are noticeable differences (this occurs 100% on startup and the fatal error text message is different), however seeing that message again after buying an entirely new CPU (and motherboard to fit it) was not a pleasant experience, to say the least.

Any answer would be appreciated; thank you for your time.

I may have possibly fixed it; I’ve been able to get to get past the crash and load properly after disabling Nvidia DLSS in the launcher (was set to automatic before) and re-enabling once in character select. Closing the game and running it with DLSS on from the launcher also seemingly works.

I’ll run a game or two and report back

Edit: completed a mission with no issues
