can't launch rstudio from a conda environment

Question

I was trying to launch rstudio from a conda environment that has R 4.1.0 and it gives me that error

This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Reinstalling the application may fix this problem.
Aborted (core dumped)

How can I solve this issue without being the admin on my computer?

One thing that I changed after creating the environment is

conda env config vars set LD_LIBRARY_PATH="/wdata/msmuhammad/workbench/miniconda3/envs/test2c2/lib"

conda env config vars set RSTUDIO_WHICH_R="/wdata/msmuhammad/workbench/miniconda3/envs/test2c2/bin/R"

I did this because I had an issue in loading Seurat before described in details in this question libstdc++.so.6: version `GLIBCXX_3.4.26' not found on Linux

when I tried exporting QT_DEBUG_PLUGINS=1 and launching rstudio again, it gave this

Any suggestions?

the command which R gives /wdata/msmuhammad/workbench/miniconda3/envs/test2/bin/R and which rstudio gives /usr/bin/rstudio

Since the source of conflict is RStudio's required dependencies being masked by the ones in the Conda environment, I'd try to see if the Qt stuff (`lib/libQt5XcbQpa.so.5`) in the Conda environment is even necessary. I run similar setup (though on MacOS), and none of my Conda R environments have Qt libraries installed. I've found Mamba's `mamba repoquery whoneeds --tree` command super useful for identifying what packages are drawing in particular dependencies. — merv, Dec 10 '21 at 20:18
