[BUG] Crash due to "syntax error: operand expected (error token is "/")" when CPU usage high (~90%)

[ardunn]

Describe the bug

Crashes on OSX when CPU usage is high.

Checking the $HOME/.config/bashtop/error.log:

New instance of bashtop version: 0.9.25 Pid: 86837
-bash: ((: Pid: Program:       Arguments:Threads: User:    Mem%       Cpu%: syntax error in expression (error token is ": Program:       Arguments:Threads: User:    Mem%       Cpu%")
-bash: ((: Pid: Program:       Arguments:Threads: User:    Mem%       Cpu%: syntax error in expression (error token is ": Program:       Arguments:Threads: User:    Mem%       Cpu%")
-bash: ((: /Library: syntax error: operand expected (error token is "/Library")
-bash: ((: /Library: syntax error: operand expected (error token is "/Library")
-bash: /: syntax error: operand expected (error token is "/")
[1]+  Done                    coproc pycoproc ( python3 ${pywrapper} )

To Reproduce

Same as the last issue I posted, I'll just copy that info here:

Installation of depedencies was exactly as under the README section Dependencies installation OSX

Then:

git clone https://github.com/aristocratos/bashtop
cd bashtop
source bashtop

Expected behavior

Bashtop should not crash.

Having the same on Archlinux with ZSH and bashtop 0.9.25 on high CPU usage:

BpyTOP seems to run smoothly.
