can't launch rstudio from a conda environment - qt

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
