What Is Going On With Unity? Weird Bugs, VS 2019 Crashing, Layout Corrupted, Installs Fails

For several weeks I have been experiencing some incredibly frustrating bugs with Unity.

1. I am getting strange errors when my otherwise error-free project loads.
Error: Mismatched serialization in the builtin class 'MonoImporter'. (Read 88 bytes but expected 92 bytes)


2. Visual Studio keeps crashing because Unity intellisense stops working for no apparent reason.

3. My Unity Layout keeps getting corrupted and 4 out of 5 times I open Unity, it fails to open and resets my layout. I have tried the suggested fixes and NOTHING is working.

4. Just now I attempted to install 2020.2.1f1 and it failed to install twice (see screenshot).

 

Definitely do NOT recommend installing tech releases, unless you enjoy debugging other people's code.

Stick with LTS if you value your time and are trying to make meaningful progress in your projects.
