How to fix error that pops every time I open my project

I recently unnistalled my old unity and now I can't quite remember which version I was on
I remember i was on 2019.2.X I installed 2019.2.11 and had to upgrade the project, which leads me to believe I had an even older version. In any case everything works except this 1 error that pops up everytime i start unity.

If someone knows how to just fix it it would save me some time trying to downgrade further along 2019.2.X until I find the correct one. ( Or is there a way to know which version my project is in? )
( If you can give me a solution to either how to fix it or how to know which version of unity I should download I would appreciate it. )

Anyway here is the error:

The message you got on starting your project mentioned what version of Unity it had been using.

 

To access version number, you can also go into your projectSettings folder and open the ProjectVersion.txt file.

As for your errors, they are all UnityEditor errors and should have no effect on your game. If you hit clear, they will go away.

 

THANKS it was 2019.2.10.f1

 

I reinstalled the correct version but the error still persists

I know its just a visual but I would really like to fix this, everytime i get out of play mode the error pops

 

Make sure the packages you are using in your project are up to date or downgrade them to the version that fits your project.

 

i just have tilemaps 2d, analytics library, and of course package manager those 3
