Upgrade made Jetbrains Rider unusable / very slow


Hey team,

Just upgraded to
JetBrains Rider 2021.1.4
Build #RD-211.7628.50, built on July 13, 2021

And now, any scripts with more than 4k lines of code are very slow, impossible to work with.
Also, using Unity 2021.1.15, Windows 10 Pro, but it was working great with the version prior to this one.
Any suggestions? Can I go back a version?
It becomes normal with no Highlight settings on, but then it is just like another notepad, LOL

Hello Alex,

Unfortunately, you have faced a known issue: RIDER-65270, as a workaround you can disable Show indentation guides in Preferences | Editor | General | Appearance. Please watch the issue for monitoring the progress and accept our apologies for the inconvinience.
