I have similar issues like this. Opening RStudio IDE stuck/freeze in Posit or RStudio logo, is it PATH problem?
For me, it freezes, but when you attempt to open a second RStudio, it usually opens fine.
Somehow, mine is fixed on its own now, but I don't know exactly how it was solved.
One thing that I uniquely attempt to do is
removing many versions of Microsoft Visual C++ Redistributable from my Windows and only installing the relevant one
Try that, uninstall RStudio, reboot, install RStudio, reboot, and then see.
