Your signature suggests you're using old versions of OCLP on your two Macs, specifically 0.6.8 & 1.4.2. Assuming that's correct, I have to ask why. Each new version of OCLP contains fixes and improvements which are not applied retroactively to older OCLP versions.
Of course, you may well have good reasons based on your local conditions. Personally I always install the latest public release of OCLP (2.4.1 at present) pretty soon after it becomes available.
Also, for persistent errors local to your m/c, before suspecting chipset problems (rare), I'd do a clean install back to the last supported version of macOS on your m/c, and update to Sequoia from there using the latest version of OCLP
