A new error in there I have not seen before
which looks like a Windows disk or file system problem!
Please do a full **clean** re-install:
- move any valued save games elsewhere, and user empire designs.txt from /Documents/Paradox Interactive/Stellaris/ if you have made any custom empires or races.
- "uninstall" in Steam-Stellaris
- manually delete both the Steam/SteamApps/common/Stellaris AND Documents/Paradox Interactive/Stellaris folders -
In particular you need to make sure there are no files or folders left under either the Steam Stellaris or Documents Stellaris locations, before installing again.
- re-install game in Steam, run a Steam Verify when done.
- add stellaris.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.
THEN run this Windows repair tool:

AND expand your Windows paging file maximum size to 32gb
On computers that have 8 GB of RAM, the suggested paging file size is 16 GB.
