Space Engineers wont launch

Hello I havent played on steam for a little while however there was a deal for all DLC and wanted to try that.

However I cant boot the game at all

When I look at the logs no errors just a warning of mscoree.dll access denied with no specified programme. Space engineers is the only file to do this but I decided to try and assist.

I have ensured Im running 4.8.1 and I have run the repair tool nothing was found and its all up to date

I have Disabled restarted and enabled forcing windows to repair using windows features which after a long wait did nothing

I have run a system file checker to see if anything could be found and nothing.

I have ensured that mscoree.dll has the righty security access

ive deactivated the antivirus and defender to try and allow but nothing

Ive verified on steam - deleted in app data and reinstalled - same issue

Ive run as admin to see if that works but nothing.

What does work is the initial version of space engineers from 2026 runs perfectly fine

However just booting the option to launch space engineers it does nothing - Steam says its running and task manger finds it but it is only memory its using nothing else.

I was hopeing to find something online but Im out of options please help

Kind regards

Kade
