Student version 2023 issues

Hi,

I recently upgraded my Solidworks student version to 2023, but some unusual issues are happening.
After creating a simple model, it does not show the part I have designed (see the file attached, name "issue". I know it is there because I can see the features on the tree.
Another issue is that the dimensions on the sketch are too small. I tried following some suggestions I found online, but I could not get the problem fixed.
