DeoxIT has been around a long time, I used it back in the late 80's/early 90's for contact issues I had with an old computer. It's definitely worth a shot, it could be some resistance induced by wear and it throws off communication just enough to cause an issue. The a1 might be more sensitive to that.
Anyway, I know it helped with the computer problem I had years ago.

Disclosure: This may or may not be relevant to this issue - My A7RIV would randomly enter focus tracking mode with the tracking box moving pretty much all over the screen, even when not in tracking mode. I use the battery grip 95% of the time and, after I power cycled the camera to stop the tracker cycling, I could tighten the retainer screw knob (minimally) which, I believe, improved the contact between the grip and the body and the problem would disappear. So, I researched electrical contact cleaners and I found products called DeoxIT made by a company called Caig Laboratories. https://caig.com/deoxit-d-series/. I ordered D, S, and G series in 7.4mL bottles. A small amount goes a long way and these small bottles may last most folks for many years. I found these products to be very effective which launched me on a project to clean and protect all of my interconnect cabling, batteries, ETC. I used the cleaner (very sparingly) on all of the gold_plated connections on all camera bodies, lenses, batteries and their contact points. I have not had the issue return since, about a year now. We live in Hawai'i and our moist tropical air is bad news for electronics and rubberized stuff. I am acutely aware of the effects of moist and/or salt air. Protect or else replace more frequently. A side benefit is that these products also lubricate and I found many connections went together easier and more smoothly than before application.
I worked in automotive Service and Parts for many years and learned about the critical nature of good, solid, clean electrical connections first hand. We used Stabilant 22 in service departments for pretty much the same purpose and, it too is pricey, but excellent. This has only intensified as vehicles are now packed with on-board computers and sensors. More often than you might think, random, intermittent problems can be corrected by assuring a sound electrical system and battery! Hope this is helpful.
