Going by your posts so far, the problems with your thesis are:

• grammar errors
• suboptimal structure
• typographical errors (swapping citations and full stops)

You have indicated nothing that makes your thesis “really bad” or that some “catastrophe“ happened. In fact, if this is all that is wrong with your thesis, it is better than most (at least).

While you might be able to publish a corrected version (replacing the published one), it is unlikely that your institution will bother about this for the kind of mistakes as assumed above. Usually this procedure is reserved for misleading theses and similar, if it exists at all.

There is a tiny chance the flaws of your thesis will be the thing that tips the scale in some future hiring decision, but that doesn’t mean that correcting them is worthwhile. Everything else you can invest your time in probably has a higher chance of benefitting your career.

After all I have seen, you appear to have an unhealthy obsession over the correctness of your thesis. I hope that realising this is all you need to let it go. I suggest that you never look at your thesis again, unless you are required to scientifically.

There is a small chance that some hiring or admission committee notices these flaws and a tiny chance that they tip the scales against you. But that doesn’t mean that correcting them is worthwhile. Everything else you can invest your time in probably has a higher chance of benefitting your career.
