Is this the entirety of your log file? Not much to work with, I'm afraid.As I surmised, there is no current se.log file, the one in that folder is from the last time SE ran correctly for me, which was on 4-29-2023
Here is the header and version number-- ever since the update things have gone haywire and it says Steam isn't running (even though it is.)
I just posted the first page because the log file hasn't changed since April since the game hasn't been able to launch since then. I'm going to delete that cache folder now, Mosfet, thanks for that suggestion. Hopefully that will help. I sent Steam Support an email because this seems to be a Steam issue not a Space Engine issue.Is this the entirety of your log file?

Find the cache subfolder inside your SpaceEngine folder, and delete it.
Use the Steam client to check for files consistency in your Spaceengine installation: From Steam Library, right-click on SpaceEngine > Properties > Local files > verify integrity of game files.
Try and run again the program, then upload here your se.log file.
I fixed the space available issue by clearing a bunch of space, enough now that I have 64 GB virtual RAM for each drive. I've been running version 43.1890 for a week straight now without any issues, although I did have to change out the config file with the one saved from last April because the game used to crash within 1 hour with the default settings. I also had to update my ship addons with my customized settings since those were not saved. I'm glad I kept all of that saved.0.990.45.1940 is not available to opt in as far as I know.
What we can't know is what really happened because the se.log doesn't contain useful info about your hardware, graphics drivers and other possible issues. What I see from what you posted is that you did have already issues back in April with 45.1940 and your program stopped right after enumerating the number of installed workshop addons (144), so it could as well be an addons issue, a graphics drivers issue, a disk drive issue because of poor amount of free disk space (and Steam has been known to cause issues if there was not enough free space) as you mentioned you don't have much space available.
As for telling Steam to not update programs, there's no straight way to do it for an indefinite amount of time, except for using Steam with the offline option, which is not a permanent solution if I remember correctly.
The SpaceEngine branch you are in now, it won't probably receive updates, so it won't update anymore.
Today, after starting Space Engine again the blue giants look normal.Blue giants are black and red for me (https://ibb.co/jytvzvD). Has anyone encountered this issue? My GPU is below minimum requirements, but other stars and planets look normal.
