After updating to Android Studio Arctic Fox, I cannot use any custom theme

Question

After updating to Android Studio Arctic Fox, I cannot choose any of my installed themes. Invalid cache and restart didn't help ;) Also reinstalling themes still not solving this problem.

I updated AS 4.2 to Arctic Fox using Toolbox on the stable channel. I'm on win 10.

Maybe someone has an idea how to solve this issue?

What I can choose:

What I have installed:

I have the same problem, so I tried installing the light theme manually. It just shows this error. I guess we have to wait for it to be updated? – Afb

I was using canary and then beta version of AS Arctic Fox on other instances and hadn't such a problem. And cyan and purple are under the JetBrains brand.. Finger cross🤞 – Weepy

Follow Simple Steps to Fix this

1. Rename the {path-of-android-studio}/lib/gson-2.7.jar file to gson-2.7.jar.disabled.
2. Restart Studio.

where {path-of-android-studio} is by default C:\Program Files\Android\Android Studio on Windows and /Applications/Android Studio.app/Contents on Mac.

The fix will be included in the next minor release of the 2020.3.1 Arctic Fox.

Answer 2

The bug still persists in release 2020.3.1 as highlighted here.

Renaming the gson-2.7.jar file works like a charm.

Answer 4

The issue still has not been fixed in 2020.3.1 Arctic Fox :(. For people using linux, If you have installed the flatpak version of android studio you can find the file in the below directory,

/home/void/.local/share/flatpak/app/com.google.AndroidStudio/x86_64/stable/945347e3ed941b868f366b6dc46cf294cafec69f21dbcb10d3fc4e69620315a4/files/extra/android-studio/lib

you don't have to go all the way to the end. Once you get to /home/void/.local/share/flatpak/app/com.google.AndroidStudio

search "gson" and the right file will come up in a second.

Unfortunately for people who used snap package to install (i honestly don't why still people use snap packages) there is no way to edit the file.

I had this issue even in 2020.3.1, I resolved this issue by simply deleting all the contents in .idea folder from my project. And updated my project kotlin version to 1.5.0.
